Future population v resources. Humans are not a plague.

Sir David Attenborough is once again in the news, arguing that humans are a plague on the earth. He has been an excellent presenter over the years, but he does himself no favours by making such claims. Doomsayers are invariably wrong. I’ve written a few times about this, but here’s a quick refresher to save you looking them up.

Let’s get rid of a silly straw man before we start – exponential growth continuing forever. Nobody sane think the Earth’s human population will carry on increasing exponentially forever. Obviously it will level off. Exponential growth all the way to infinity isn’t sustainable, but since the population will level off around 10 billion, we really don’t need to spend too much time worrying about the mathematics of infinite consumption. I would personally put the maximum capacity of the Earth at around 100 billion, but I don’t expect us ever to have more than 10 billion here, and nobody sensible does. Other planets will house some more, but they will have their own economics.

First, we aren’t running out of physical resources, just moving them around. Apart from a few spacecraft that have moves some stuff off planet, some excess radioactive decay induced in power stations and weapons, and helium and hydrogen escaping from the atmosphere, all of which is offset by meteorites and dust landing from space, all we have done is convert stuff to other forms. Almost all materials are more plentiful now than they were 40 years ago when Sir David’s predecessors warned of the world running out imminently. They were wrong, so is he. If we do start to run short, we can mine key elements from rubbish tips and use energy to convert back to any form we need. We can engineer substitutes  And we can gather them from space. Another way of looking at this issue is that we live on top of 6000km of resources and only have homes a few metres deep. When we fill them, which doesn’t take much, we dispose of one thing to make room for a new one. Recycling technology is getting better all the time, at the same time as material technology means we need less stuff to make something, and can do so with a wider range of input elements.

We are slowly depleting some organic resources. For example, fossil fuels, but there are several hundred years supply left, and we will not need any more than a tiny fraction of that before we move to other energy sources. Also, fish, many stocks are threatened around the world, so fishing needs some work in designing and implementing better practices, but that is not unachievable by any means. Forestry is being depleted in some areas and expanding in others. Some of the areas that are being wiped out are because environmentalists and other doomsayers have forced daft policies through that perversely encourage people to burn forests down to make the land available for biofuel plantations and carbon offset schemes.

We certainly are not short of space. If the inhabitable land in the world were inhabited at the same density as southern England, we could house 70-80 billion people. The UK sometimes feels full when we get stuck in traffic jams or queues for public services, but these are mainly a matter of design. Self driving vehicles can increase road capacity by a factor of 5, regional rail capacity by a factor of 200. Replacement of most public sector workers by machines, or better still, good system design, would eradicate most queues and improve most services.

Energy isn’t a problem in the long term in spite of what doomsayers claim. Shale gas is already reducing costs in the USA at the same time as reducing carbon dioxide emissions. In Europe, where doomsayers and environmentalist have more power to influence policy, CO2 emissions are increasing while energy costs threaten many areas of the economy. Obama’s recent speech threatens to undermine the USA’s advantage but that’s another story. Nuclear energy currently depends on uranium  but thorium based power is under development and is very likely to succeed in due course, adding several hundred years of supply. Solar, fusion, geothermal and shale gas will add to this to provide abundant power for even a much great population, within a few decades, well ahead of the population curve. The only energy shortages we will see will be doomsayer-induced.

Future generations will face debts handed on to them without their consent, but will also inherit a physical and cultural infrastructure with built in positive feedback that ensure rapid technological development. Among its many benefits, future technology will greatly reduce the amount of material needed to accomplish a task. It will also expand the global economy to provide enough wealth to buy a decent standards of living for everyone. It will also clean up the environment  It will also produce far more food from less land area, allowing land to be returned to nature. Food production per hectare has doubled in the last 30 years. The technology promises further gains  into the foreseeable future.

The world Attenborough is scared of will actually be a greener and more pleasant land, with nature in a better state than today, with a larger world population that is richer and better fed, almost certainly no more than 10 billion. Providing that is, that we can stop doomsayers forcing their policies through – the only thing that would really wreck the environment. A doomsayer-free human population is not a plague but a benefit to the Earth and nature. The doomsayers themselves and their daft policies are the greatest proven threat. If Sir David really cares about nature, he should focus on letting us be inspired by nature as he does so brilliantly, and let technologists get on with making sure it can flourish in the future

 

 

Future food production

Food production is adapting to increased environmental awareness, but we will see far more change over coming years.

There is a lot of innovation right now in food production. Hydroponics is growing, as are vertical farms, home growing and focus on local production that is encouraging cottage industry specialists. There are some nice synergies. Greenhouses can make good use of waste heat from power stations and also benefit from the CO2 given off if they burn fossil fuels, which of course is locked up when the plants convert it to biomass. This effectively increases the energy efficiency of the power station by adding an extra layer of chemical energy recovery after thermal. There are many articles already out there about hydroponics etc so I don’t need to repeat them here. That’s what Google is for.

The web makes it easy for producers of all kinds to have a closer relationship with customers, so it is now possible to organise local marketing and distribution around social networking, with groups of customers even commissioning crops grown according to specific regimes. GPS-enabled tractors can treat each square metre of a field effectively as a different managed allotment. With people more interested in exactly how their food is produced, this is sure to find a healthy market as the economy recovers.

At higher levels, financial strain during the lengthy recession is forcing many people to commercialise their hobbies, such as baking or catering, creating a growing home-made sector. This will even extend into arts ad crafts thanks to new technology such as 3D printing, which will make its way into the kitchen any time soon.  So the emerging pattern is one of rapidly increasing diversity in food production, from crop growing to processed foods manufacture. This creates opportunities for increased competition in the food space, but also presents risks to existing manufacturers. As ever with any kind of turbulence, the winners and losers will be decided by how willing and able companies are to adapt.

Vertical farms on the walls of tall buildings add agricultural space to cities and as well as growing food, also helps air quality. The food would be of dubious taste and value if air were polluted as badly as it used to be, but with emissions now, it is probably OK. A variety of mechanisms have been suggests for vertical farms. Some look more feasible than others, but the general idea seems workable, and experimentation and development will sort out which solutions work best. One thing that is easy to forget though is that the amount of sunlight incident on a given land area doesn’t depend on the building architecture raised on it, and using a wall gives a lower energy density than a field or a roof because the same total light is spread over a larger area. Interior farms of course need artificial light, but if that is produced via nuclear energy, then it might still work out well environmentally.

Home finishing is a good prospect too. Many people are already used to part bake products, where they buy a product that is already mostly prepared and just needs finishing off in the oven to make one with all the benefits of freshly made cuisine. Microwave and other ready-meals are even more familiar. 3D printing technology may even have a future role, making edible frills and accessories to brighten up appearance.

Home finishing could be done as a small local business too. Large manufacturers could gain local presence for fresh produce by using local finishers, and these could be ordinary households or based in small offices or shops, making a new cottage industry. They could also work well with local manufacturing and distribution companies. Social networks could provide most of the platform for these local business clouds but they could also be based on systems run by large companies.

This social potential is useful if people rebel against the multinationals at some point. With frequent problem areas like tax avoidance, misleading information, exploitation and other issues that are setting people against them, having a fall-back position increases leverage by showing that communities are not powerless.

Current biotechnology research into lab-grown meat might eventually flourish into a large meat manufacturing industry. It is hard to tell yet how successful it might be in creating cost effective, healthy and palatable solutions. Vegetarian meats would presumably see a good market since many vegetarians avoid meat mainly because of the ways animals are reared and treated, and many meat eaters also have some reservations and would be willing to switch. Lab-grown meat would be little different from a yoghurt in terms of its cruelty implications. Although the principle has been proven, much work is need to replicate textures and taste well at a reasonable cost.

Lab-grown meat could be more energy efficient than that produced by animals, and would liberate farmland for crops. Together with increasing productivity in crop production anyway, some expect that we will be able to start returning land to nature in the second half of this century because we will make plenty of food for everyone with less land.

Biotech will create new varieties of crops, some with extra vitamin content or other health benefits, lower fat animals and enable varieties that are adapted to a wider range of climates, thereby increasing the amount of land that could be used for agriculture.

Home printer technology also is being hyped for food production, or rather assembly is probably a more accurate description, since nobody is yet suggesting its use for making the raw materials such as proteins and carbohydrates.  Its is effectively the next level up in abstraction from the lab grown products. Even chocolate could be made using printers. Food printers could only ever be a niche market, but could sit alongside other home gadgets such as microwaves and mixers. Cakes, confectionery,  frills and accessories would be the probable markets. It would especially appeal to the kinds of people who make elaborate cake decorations and could extend creative food design to a much broader group.

Food technology will continue to other areas too, making more appealing products from even wider range of raw materials. GM bacteria or algae could compete well with land grown crops. Algae may be grown at sea as part of carbon reduction schemes anyway, and could be used for either biofuel or as a component for food production. Of course, many foods contain lots of ingredients, so even if it isn’t suitable as a main platform, such humble starting points may be a used as fillers or other additives.

Of course, fish farming is bound to increase too. Many fish species are threatened today and near extinction of a key species does eventually force governments to listen and act. Although regulation so far has at best been poor, it can only improve and perhaps we may soon have a global set of treaties that ensure sustainable fishing and farming. There will also be a place for GM fish that maybe grow faster or breed faster. Some countries will be more willing to accept GM than others but when the choice is high prices v GM, GM will win out.

Casual displays

I had a new idea. If I was adventurous or an entrepreneur, I’d develop it, but I’m not, so I won’t. But you can, before Apple patents it. Or maybe they already have.

Many people own various brands of pads, but they are generally expensive, heavy, fragile and need far too much charging. That’s because they try to be high powered computers. Even e-book readers have too much functionality for some display purposes and that creates extra expense. I believe there is a large market for more casual displays that are cheap enough to throw around at all sorts of tasks that don’t need anything other than the ability to change and hold a display.

Several years ago, Texas Instruments invented memory spots, that let people add multimedia to everyday objects. The spots could hold a short video for example, and be stuck on any everyday object.These were a good idea, but one of very many good ideas competing for attention by development engineers. Other companies have also had similar ideas. However, turning the idea around, spots like this could be used to hold data for a  display, and could be programmed by a similar pen-like device or even a finger touch. Up to 2Mb/s can be transmitted through the skin surface.

Cheap displays that have little additional functionality could be made cheaply and use low power. If they are cheap enough, less than ten pounds say, they could be used for many everyday purposes where cards or paper are currently used. And since they are cheap, there could be many of them. With a pad, it has to do many tasks. A casual display would do only one. You could have them all over the place, as recipe cards, photos, pieces of art, maps, books, body adornment, playing cards, messages, birthday cards, instructions, medical advice, or anything. For example:

Friend cards could act as a pin-board reminder of a friend, or sit in a wallet or handbag. You might have one for each of several best friends. A touch of the spot would update the card with the latest photo or status from Facebook or another social site. Or it could be done via a smart phone jack. But since the card only has simple functionality  it would stay cheap. It does nothing that can’t also be done by a smartphone or pad, but the point is that it doesn’t have to. It is always the friend card. The image would stay. It doesn’t need anything to be clicked or charged up. It only needs power momentarily to change the picture.

There are displays that can hold pictures without power that are postcard sized, for less than £10. Adding a simple data storage chip and drivers shouldn’t add significantly to cost. So this idea should be perfectly feasible. We should be able to have lots of casual displays all over our houses and offices if they don’t have to do numerous other things. In the case of displays, less may mean more.

The future of the Olympics, in 2076

Now that it is all over, it is time to think about the future. The last time the Olympics was held in London was 1948, 64 years ago. Going 64 years in the future, what will it be like then?

Watching the Olympics on 3D web TV is about as advanced as it gets today. By the 2024 Olympics, it will be fairly common to use active contact lenses with lasers writing images straight onto your retinas. It will be fully immersive, and almost feel like you’re there. In fact, many of the people in the crowd at the games will also use them, to zoom in or watch replays and extra content. The 2028 Olympics will have the first viewers using primitive-but-fun active skin technology to connect their nervous systems so that they can even feel some of the sensations involved. In gyms up and down the land, runners will be able to pretend they are in the race, running on their treadmills virtually against actual Olympians. They’ll receive their final placing against the others doing the same. This will improve and by 2040 even domestic active skin sensation recording and replay will feel very convincing. By 2076, we’ll have full links between IT and our brains, living the events as if we were athletes ourselves, Total Recall style.

Interfacing to the nervous system will help potential Olympic athletes improve their performance quickly, injecting sensations into the body to make perfect movements just feel better, so their body learns the optimal movement quickly. This will show the first improvements in results in 2032, with heptathletes and decathletes performing almost perfectly in every one of their events.

The 2050 Olympics will see the first competitors who are children of genetically enhanced parents, and some genetically enhanced themselves. They won’t need drugs to out-perform even those regular humans who have overdosed on steroids all their careers. Their careers will last longer too, as biological decline will be less of an issue thanks to their genes. In the same timeframe, drugs will advance enormously too, squeezing extra levels of performance, learning speed, sensory awareness and muscle development. With negative side effects under control, some drugs and implants may be accepted in sports. But fierce arguments over fairness will eventually force a split between the various streams.

The 2076 Olympics will be made up of five events. There will be one ‘original Olympics’ for ordinary unmodified humans, tested thoroughly for any genetic or chemical enhancements, forced to use the same equipment to eliminate technological advantage, possibly given handicaps for any innate genetic advantage they have over the competition. There will be another for the disabled, many of whom will resist being made ‘normal’, even if technology permits. There will be another for robots, with advanced AI and a range of ‘body types’, used as a show-off event for technology companies. Another stream will take place one for un-enhanced athletes using advanced drugs, implant technology, superior equipment, and even externally linked  IT to gain technological advantage and make more exciting sport. It will be far from ‘natural’, but viewers won’t care. And finally, another event for biologically and neurally enhanced super-humans, without any other technology advantage. These streams couldn’t compete fairly head on, but will make distinct events with distinct flavours and advantages.

The spirit of The Games will live on even with this split, and still only the very best will be able to compete, but they will be bigger, better and more exciting for everyone.

Population growth is a good thing, updated July 2012

This has been my most popular blog article so far so here is an updated version, since the original is 18 months old now. No big changes, mainly a tidy-up, with a long overdue promised section on biological resources added at the end.

Many people are worried now that we have passed the 7Bn mark for world human population, that we are overpopulating the planet and will reap environmental catastrophe. Some suggest draconian measures to limit or even reduce it. I am not panicking at all, and refuse even to be particularly concerned. I don’t think it is necessarily a bad thing to have a high population. And to use the doom-monger’s favourite term, sustainable, I think it will be entirely sustainable. OK, so, point by point, here is why.

Population is certainly growing rapidly, and will continue till it levels off around 9.5 billion by about 2050. Then it will start to fall. But let’s not treat 9.5Bn as if it is a major catastrophe. Doom-mongers are predicting mass starvation, riots and so on, as doom mongers enjoy doing. But is it so bad? Let’s put it in perspective a bit. I live in the South of England. When I go on walks with my wife I will typically meet only a few people on the way; mostly it will be empty countryside and most of the time we won’t be able to see a single building or road. I do not feel it is terribly overpopulated here yet, even with the second highest population density on Earth, at 470 people per square kilometre. India only has 345, even with its massive population. China has even less at only 140, while Indonesia has 117,  Brazil just 22, and Russia a mere 7.4 people per square kilometre. Yet these are the world’s biggest populations today. Room for expansion perhaps. If all the inhabitable land in the world were to be occupied at average English density, the world can actually hold 75Bn people. There would still be loads of open countryside, still only 1 or 2% covered in concrete and tarmac. So let’s stop first of all from imagining that we are running out of space any time soon. We just aren’t!  We panic in the UK because we see the uncomfortable end of extreme inequality in global distribution of people, but that will self limit. If it becomes too dense, people will stop immigrating.

Secondly, westerners’ (i.e. relatively wealthy people’s) houses have typically 5 or 6m deep of living space. They live on top of 6000km deep of materials. So do their neighbours. Not all of it is useful, but it is really hard to see why there is so much panic about physical resources when they lie so deep under our feet. When we discard them, they are still there, just repositioned. If you buy stuff, your house quickly fills up and you have to throw something out to make space before you buy more. It gets recycled or thrown on landfill, which could become a  future mine if materials ever did become scarce enough. A few spacecraft have left the earth forever over the years, taking a few tons of material away, but space dust occasionally lands too, so actually there are more physical resources on Earth than there were before people came into being. Organic resources such as forests and fisheries are a different matter. I’ll look at them later in this article. It won’t change the balance of the argument because we will learn to manage them better.

But of course, if everyone wants to live to westerns standards, the demands on the environment will grow as the poor become richer and able to afford more. If we try to carry on with existing technology, or worse, with yesterday’s, we will not find it easy. Those who consider technology and economic growth to be enemies of the environment, and who therefore would lock us into today’s or yesterday’s technology, would condemn not only billions of people to poverty and misery but also force those extra people to destroy the environment to try to survive. The result would be miserable future for humanity and a wrecked environment. Ironically, they have the audacity to call themselves environmentalists or greens, but they are the true enemies of the earth, and of humanity. If we ignore such lunacy as we should, and allow progress to continue, we will see steady global economic growth that will result in a higher average income per capita in 2050 with 9.5Bn people than we have today with only 7Bn. The technology meanwhile will develop so much that the same standard of living can be achieved with far less environmental impact. For example, bridges hundreds of years ago used far more material than today’s , because they were stuck with primitive science and technology. Technology is better now and needs less material, and is better for the environment. With nanotechnology and improved materials, we will need even less material to build future bridges. The environmental footprint of each person will certainly be far lower in 2050 if we accept new technology than it will be if we restrict growth and technology development. It will almost certainly be less even than today’s, even though our future lifestyles would be far better. Trying to go back to yesterday’s technologies without greatly reducing population and lifestyle would impose such high environmental impact that the environment would be devastated. We don’t need to, and we shouldn’t.

Take TVs as another example. TVs used to be hugely heavy and bulky glass monsters that took up half the living room, used lots of electricity, but offered relatively small displays with a choice from just a few channels. Today, thin LCD/LED displays use far less material, consume far less power, take up far less space and offer far bigger and better displays offering access to thousands of channels via satellites and web links. So as far as TV-based entertainment goes, we have a higher standard of living with lower environmental impact. The same is true for our phones, computers, networks, cars, fridges, washing machines, and most other tools. Better materials enable lower use. New science and technology has enabled new kinds of materials that can substitute for scarce physical resources. Copper was once in danger of running out imminently. Now you can build a national fibre telecommunication network with a few bucketfuls of sand and some plastic. We have plastic pipes and water tanks too, so we dont really need copper for plumbing either. Aluminium makes reasonable cables, and future materials will make even better cables, still with no copper use. There are few things that can’t be done with alternative materials, especially as quantum materials can be designed to echo the behaviour of many chemicals. It is highly unlikely that we will ever run out of any element. We will simply find alternative solutions as shortages demand.

Oil will be much the same story. To believe the doom-mongers, our use of oil will continue to grow exponentially until one day there is none left and then we will all be in big trouble, or dead, breathing in 20% CO2 by then of course. Again, nonsense. By 2030, oil will be considered a messy and expensive way of getting energy, and most will be left in the ground. The 6Gjoules of energy a barrel of oil contains could be made for $30 using solar panels in the deserts, and electricity is clean. Cheap electricity won’t come from our UK rooftops as current incentivised by our green-pressured government, but somewhere it is actually sunny, deserts for example, where land is cheap, because it isn’t much use for anything else. The energy will get to us via superconducting cables. Sure, the technology doesn’t yet exist, but it will. Oil will only cost $30 a barrel because no-one will want to pay more than that for what will be seen as an inferior means of energy production. Shale gas might still be used because it produces relatively little CO2 and will be very cheap, but even that will start declining as the costs of solar and nuclear variants fall.

By the time we get to our 2050 world with 9.5Bn people, fusion power will be up and running, alongside efficient solar (perhaps some wind) and other forms of energy production, proving an energy glut that will help with water supply and food production as well as our other energy needs. In fact, thanks to the development of graphene desalination technology, clean water will be abundantly available at low cost (not much more than typical tap-water costs today) everywhere. Our technologies will be so advanced by then that we will be able to control climate better too. We will have environmental models based on science, not eviro-religion. So we will know what we’re doing rather than acting on guesswork and old-wives’ tales. We will have excellent understanding of genetics and biotech and be able to make superior crops and animals, so will be able to make enough food to feed everyone, ensuring not only quantity but nutritional quality too. While today’s crops deliver about 2% of the solar energy landing on their fields to us as food, we will be able to make foods in factories more efficiently, and will have crops that are also more efficient. It is true that we may see occasional short-term food shortages, but in the long term, there is absolutely no need to worry about feeding everyone. And no need to worry about the impact on the environment either, because we will be able to make more food with far less space. No-one needs to be hungry, even if we have 9.5Bn of us, and with steady economic growth, everyone will be able to afford food too. This is no fanciful techno-utopia. It is entirely deliverable and even expectable. All around the world today, people’s ethical awareness is increasing and we are finally starting to address problems of food and emergency aid distribution, even in failing regimes. The next few decades will not eradicate poverty completely, but it will make starvation much less of a problem, along with clean water availability.

How can we be sure it will be developed? Well, there will be more people for one thing. That means more brains. Those people will be richer, they will be better educated, many will be scientists and engineers. And many will have been born in countries that value engineers and scientists greatly, and will have a lot of backing, so will get results. And some will be in IT, and will develop computer intelligence to add to the human effort, and provide better, cheaper and faster tools for scientists and engineers in every field to use. So, total intellectual resources will be far greater than they are today. Therefore we can be certain that technological progress will continue to accelerate. As it does, the environment will become cleaner and healthier, because we will be able to make it so. We will restore nature. Rivers today in the UK are cleaner than 100 years ago. The air is cleaner too. We look after nature better, because that’s what people do when they are affluent and well educated. In 50 years time we will see that more widespread. The rainforests will be flourishing, some species will be being resurrected from extinction via DNA banks. People will be well fed. Water supply will be adequate. But all this can only happen if we stop following the advice of doom-mongers and technophobes who want to take us backwards.

That really is the key: more people means more brain power, more solutions, better technology. For the last million years, that has meant steady improvement of our lot. In the un-technological world of the cavemen hunter-gatherers, the world was capable of supporting around 60 million people. If we try to restrict technology development now, it will be a death sentence. People and the environment would both suffer. No-one wins if we stop progress. That is the fallacy of environmental dogma that is shouted loudly by the doom mongers. Some extremists in the green movement would have us go back to yesterday, rejecting technology, living on nature and punishing everyone who disagrees with them. They can indulge such silliness when they are only a few and the rest of us support them, but everyone simply can’t live like that. Without technology, the world can only support 60 million. Not 7 billion or 9.5 billion or 75 billion. There simply aren’t enough nice fields and forest for us all to live that way.

It is a simple choice. We could have 60 million thoroughly miserable post-environmentalists living in a post eco-catastrophe world where nature has been devastated by the results of stupid policies invented by so-called environmentalists, and trying to make a feeble recovery. Or we can ignore their nonsense, get on with our ongoing development, and live in a richer, nicer world where 9.5Bn people (or even far more if we want) can be happy, well fed, well educated, with a good standard of living, and living side by side with a flourishing environment, where our main impacts on the environment are positive. Technology won’t solve every problem, and will even create some, but without a shadow of a doubt, technology is by far nature’s best friend. And ours. Not the ‘environmentalists’, many of whom are actually among the environment’s worst enemies – at best, well-meaning fools.

And there is one final point hat is always overlooked in this debate. Every new person that is born is another life, living, breathing, loving, hopefully having fun, enjoying life and being happy. Life is a good thing, to be celebrated, not extinguished or prevented from coming into existence just because someone else has no imagination. Thanks to the positive feedbacks in the development loops, 50% more people means probably 100% more total joy and happiness. Population growth is good, we just have to be more creative, but that’s what we do all the time. Now let’s get on with making it work.

Good times lie ahead. We do need to fix some things though.

I mentioned that physical resources won’t diminish significantly in quantity in terms of the elements they hold at least, though those we use for energy (oil, coal and gas) give up their energy when we use them and that is gone. However, the ecosystem is a different matter. Even with advanced genetic technology we can expect in the far future, it will be difficult to resurrect organisms that have become extinct, and far better to make sure they don’t. Even though an organism may be brought back, we’d also have to bring back the environment it needs with all the intricately woven inter-species dependencies. Losing a single organism might be relatively recoverable, but losing a rain forest will be very hard to fix. Forests are very complex systems. In fact designing and making a synthetic and simpler rainforest is probably easier than trying to regenerate a lost natural one. We really don’t want to have to do that. It would be far better to make sure we preserve the existing forests and other complex ecosystems. Poor countries may reasonably ask for some payment to preserve theirs rather than chopping them down to sell wood. We should also make sure to remove current incentives to chop them down to make room for palm oil plantations to satisfy the demands of poorly thought out environmental policies in rich countries.

The same goes for ocean ecosystems. We are badly mismanaging many fisheries today, and that needs to be fixed. There are certainly some signs of progress.  Silly EU regulations that cause huge quantities of fish to be caught and thrown back dead into the sea will soon be history. Again, these are a hangover from previous environmental policy designed to preserve fish stocks, but again this was poorly thought out and has had the opposite result. Other policies in the EU and in other parts of the world are also causing problems by unbalancing populations and harming or distorting food chains. The bans on seal hunting are good – we love seals, but the explosion is seal populations caused by throwing dead fish back has increased the demand of the seal population to over 100,000 tons of fish a year, when it is already severely stressed by over-fishing. The dead fish have also helped cause an explosion in lobster populations and in some sea birds. We may appreciate the good side, but we mustn’t forget to look for harmful effects that may also be caused. It is obvious that we could do far better job, and we must. A well-managed ocean with properly designed farms should be able to provide all the fish and other seafood we need, but we are well away from it yet and we do need to fix it.

With ongoing scientific study, understanding or relationships between species and especially in food chains is improving, and regulations are slowly becoming more sensible, so there is hope. Many people are switching their diets to fish with sustainable populations. But these will need managed well too. Farming is suitable for many species and crashes in some fish populations have added up to a loud wake-up call to fix regulations around the world. We may use genetic modification to increase growth and reproduction rates, or otherwise optimise sustainability and ocean capacity. I don’t think there is any room for complacency, but I am confident that we can and will develop good husbandry practices and that our oceans and fish stocks will recover and become sustainable.

Certainly, we have a greater emotional attachment to the organic world than to mere minerals, and we are part of nature too, but we can and will be sustainable in both camps, even with a greatly increased population.

 

Future sports

Training

Today it takes many years of training to get to the top of any field of sports. In the future it could be a whole lot faster thanks to progress in three areas of technology – biotech, nanotech and IT. Miniaturisation in IT, thanks to nanotechnology, will continue to the point where electronics can be printed onto the skin surface. So you may get a display on your arm, like a video tattoo, showing you how well you are doing, showing your heart rate, temperature, blood chemistry and so on and displaying any relevant warnings. Not long after that, electronics can be blasted into the skin, so that it is contact with blood capillaries and nerve endings. With this technology, called Active Skin, athletes could have their body condition monitored all the way through a session to help optimise the balance of effort over the duration of the event and to help them choose the right dietary supplements. So problems of giving too much or too little at a particular point could be identified and fixed. But more excitingly, nerve signals could also be recorded from individual nerve endings, and recreated by computer later. So, a novice golfer or tennis player would try to copy the swing that their pro is showing them, and a computer could create nerve inputs, creating discomfort when they deviate from the perfect movement. So the perfect swing with feel right and any other will feel wrong. As an extra aid, active contact lenses will be able to create 3d images directly into the athlete’s eyes, showing them exactly what they are doing and superimposing what they should be doing. They would be able to see their body position precisely, with any deviations highlighted and amplified with mild discomfort. With practice, doing what feels right will generate the right movement every time. With such training aids, progress from novice to expert could be a matter of weeks rather than years. This will certainly help people to quickly reach their potential, and to get more out of the sports they participate in, but it will also allow the top pros to extract every last bit of potential from their bodies. If they could do a little better by changing one tiny little thing, the computer will be able to help identify it, and help them address the imperfection. So professional sport will improve too.

We’ll also see computer game technology coming down the same route. Physiotherapists are already using Wii machines to treat stroke patients by helping them learn movement again through sports games. Taking this forward, we will certainly start seeing some hybrid sport evolve, with lots of top level physical activity in combination with the computer game. Top skiers would be able to practice different runs all the year round, with the computer recreating all the sensations of doing it for real as well as the full 3d video. So by the time they even get there, they will have had hours of computer assisted training on the run. Who knows, maybe the top level of sports in the future might not even take place on real snow, but in fantastic computer simulations of imaginary, more challenging environments

Nutrition

Top performance depends on a lot of things, and getting proper nutrition is one of the most important, both during training and right up to the main event. At the moment, athletes don’t get enough data on exactly what happens in their bodies while they are performing. New technologies in the biotech industry will change that soon. Already, special chips, developed for genetic analysis, can identify chemicals with just a couple of molecules. As ongoing development inevitably takes this level of monitoring capability into everyday training, athletes will soon be able to see exactly how their body behaved all the way through a session. Even during a session, if something is running low, they could be warned, and perhaps change their behaviour accordingly. Computers would be able to identify exactly what nutrition an athlete should take before a performance to put the body in perfect condition for the event.

The release of energy and nutrients over time varies enormously among foodstuffs as they break down at different rates. Athletes already take different foodstuffs to keep them going during different parts of an event. Again, new developments borrowed from the biotech industry will allow nutrients to be packaged in microcapsules that enter the blood during normal digestion, and which can then be ruptured on receiving a special signal from a computer, allowing a perfectly tailored delivery of nutrients into the blood just as the athlete needs them. Just how far such electronically assisted nutrition goes depends on regulation.

Making the right proteins and vitamins in the first place is also changing. Rather than producing batches of chemicals and pills, genetic modification is developing nicely, and already a commonplace technology and already a whole range of plants will be grown specifically to optimise particular protein or vitamin content. Athletes can also go to a clinic and have their genes tested, helping their doctors and trainers to identify a highly personalised regime to get exactly the right nutrition for that person and that event, even to the extent of tackling some medical conditions. They will then be able to commission foodstuffs grown to their own needs and personal specification. They will still have their own genetic limitations, but at least they can go all the way to the limits of their personal potential. And it is likely that in some events, there may be  handicap systems that take account of genetic limitations to allow athletes to compete on a level playing field. Sport would then become about reaching your natural limits, rather than just been born with some genetic advantages.

Personalised and optimised nutrition regime stands in stark contrast to today’s increasing obesity, but new foodstuffs promise to make dents in that too, as does the rising popularity of computer games that involve vigorous physical activity. Playing electronic sports on the net against other people could well be one of the next big social networking trends, maybe even becoming the 21st century version of the gym, or more probably being incorporated into gym technology to make it as much fun there as staying with the games console at home. Hopefully obesity will start levelling off soon and start to decline.

Psychology

With all the technology advances over the last few millennia, our psychology probably hasn’t changed much since we were cavemen. Sport appears to be a symbolic form of hunting or combat designed to demonstrate skill and bravery and to win a higher place in the pecking order, or bind a tribe together. At a deep level, people still want to win, to be top dog, to have the admiration of the crowd, to win prizes and to feel the close bonds of hunting or fighting together. I don’t think that is going to change, even with future technology. Better tools and better locations will only change the nature of the game, not the psychological incentives to perform heroically.

Future training equipment will include thought recognition and nervous system links to gather information on neurological and mental activity. If our champions are not giving it their all, it will show on the readout. And in the far future, when brain add-on devices can enhance people’s minds, even if they are not allowed in sporting events , they might be permitted during training. But none of this changes the fundamental nature of the person underneath. The degree of motivation they experience when faced with a challenge, the possibility of winning a prize, or the possibility of losing, goes deeper than technology can reach. These are part of the nature component in the formula, so as with physiology, it takes a good trainer with the right tools, in the right environment, to bring them fully to the surface. Champions are champions partly because their inner motivation is stronger and they will push themselves even harder than their competitors.

But I still think there is a missing component in the equation, the roar of the crowd. Champions will manage to find the last tiny bit of heroic effort only when the crowd demands it. At a live event with a big audience, there is no problem, but when the main crowd is only there via TV or the net, I suspect that the performance will be less. If we can somehow bring the crowd deeper into their perception while they compete, maybe they can perform better. But full sensory immersion technology can bring the crowd from the living room into the competitors’ presence.  Active contact lenses will allow athletes to see the crowd, ear implants will allow them to hear them roar. Then they will still feel the atmosphere even in an empty arena. Only then will the ancestral tribal motivations kick in fully.

Finally, we will one day see androids competing in sports, and though they will normally compete against each other, there will be demands to have humans compete with them. When this happens, our champions will want to win in defence of humankind, the ultimate crowd. I think we will be able to give androids emotions too. If we design them to be similar in physical performance, and give them similar psychology, maybe we could have a very interesting contest indeed.

Making a champion

People have debated for millennia what it is that makes a sporting hero into a real champion. How can people be compared when they competed in different sports, in different periods? Some of the equations hold some merit, other don’t. Here is my take, based on the above.
