what elements in the human or natural environment were important to your daily life?

E arth is home to millions of species. Simply one dominates information technology. Us. Our cleverness, our creativity and our activities take modified nigh every part of our planet. In fact, we are having a profound touch on it. Indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. And every i of these problems is accelerating as we proceed to abound towards a global population of x billion. In fact, I believe nosotros can rightly call the situation we're in right now an emergency – an unprecedented planetary emergency.

Nosotros humans emerged as a species most 200,000 years ago. In geological fourth dimension, that is really incredibly recent. Just 10,000 years ago, there were i million of united states. By 1800, just over 200 years ago, there were 1 billion of the states. By 1960, l years ago, there were 3 billion of usa. There are at present over 7 billion of us. By 2050, your children, or your children's children, will exist living on a planet with at least 9 billion other people. Some time towards the end of this century, there will be at least 10 billion of us. Possibly more.

We got to where nosotros are now through a number of civilisation- and lodge-shaping "events", most notably the agronomical revolution, the scientific revolution, the industrial revolution and – in the Westward – the public-wellness revolution. By 1980, there were 4 billion of us on the planet. Only 10 years after, in 1990, there were v billion of us. By this signal initial signs of the consequences of our growth were starting to testify. Non the to the lowest degree of these was on h2o. Our demand for water – not just the h2o we drank but the water we needed for food production and to make all the stuff we were consuming – was going through the roof. But something was starting to happen to water.

Back in 1984, journalists reported from Ethiopia about a dearth of biblical proportions caused by widespread drought. Unusual drought, and unusual flooding, was increasing everywhere: Australia, Asia, the United states of america, Europe. H2o, a vital resource we had thought of as arable, was now suddenly something that had the potential to be scarce.

By 2000 there were 6 billion of us. It was becoming clear to the earth's scientific customs that the accumulation of COtwo, methyl hydride and other greenhouse gases in the temper – as a effect of increasing agronomics, land utilise and the production, processing and transportation of everything nosotros were consuming – was irresolute the climate. And that, as a outcome, we had a serious trouble on our hands; 1998 had been the warmest year on record. The 10 warmest years on record have occurred since 1998.

We hear the term "climate" every twenty-four hour period, so information technology is worth thinking about what we actually mean by it. Obviously, "climate" is not the same every bit atmospheric condition. The climate is one of the Globe's central life support systems, one that determines whether or not we humans are able to live on this planet. Information technology is generated by 4 components: the temper (the air we breathe); the hydrosphere (the planet'southward water); the cryosphere (the ice sheets and glaciers); the biosphere (the planet's plants and animals). Past at present, our activities had started to alter every one of these components.

Our emissions of COtwo modify our atmosphere. Our increasing h2o use had started to modify our hydrosphere. Rising atmospheric and sea-surface temperature had started to modify the cryosphere, most notably in the unexpected shrinking of the Arctic and Greenland ice sheets. Our increasing employ of state, for agronomics, cities, roads, mining – too as all the pollution we were creating – had started to modify our biosphere. Or, to put information technology some other way: nosotros had started to change our climate.

In that location are now more than than seven billion of united states of america on Earth. As our numbers go along to grow, we continue to increment our demand for far more than water, far more than food, far more than state, far more ship and far more than free energy. As a upshot, we are accelerating the rate at which nosotros're changing our climate. In fact, our activities are not only completely interconnected with but now besides interact with, the circuitous organization we live on: Globe. It is important to understand how all this is connected.

Let's accept i of import, withal petty known, aspect of increasing water use: "hidden h2o". Hidden water is water used to produce things nosotros consume but typically do non recall of as containing water. Such things include chicken, beefiness, cotton, cars, chocolate and mobile phones. For example: it takes around iii,000 litres of water to produce a burger. In 2012 around five billion burgers were consumed in the UK alone. That's fifteen trillion litres of h2o – on burgers. Simply in the U.k.. Something like 14 billion burgers were consumed in the United States in 2012. That'southward around 42 trillion litres of water. To produce burgers in the The states. In one twelvemonth. It takes around nine,000 litres of water to produce a chicken. In the UK solitary we consumed around one billion chickens in 2012. It takes effectually 27,000 litres of water to produce one kilogram of chocolate. That's roughly ii,700 litres of water per bar of chocolate. This should surely exist something to call back nigh while y'all're curled upwardly on the sofa eating it in your pyjamas.

But I have bad news nigh pyjamas. Because I'm agape your cotton pyjamas accept 9,000 litres of water to produce. And it takes 100 litres of water to produce a cup of java. And that's before whatever water has actually been added to your coffee. Nosotros probably drank about xx billion cups of coffee concluding twelvemonth in the United kingdom of great britain and northern ireland. And – irony of ironies – it takes something like four litres of water to produce a one-litre plastic bottle of water. Last twelvemonth, in the UK lonely, we bought, drank and threw away ix  billion plastic water bottles. That is 36 billion litres of water, used completely unnecessarily. Water wasted to produce bottles – for water. And it takes around 72,000 litres of water to produce i of the 'chips' that typically powers your laptop, Sabbatum Nav, phone, iPad and your car. There were over 2 billion such chips produced in 2012. That is at to the lowest degree 145 trillion litres of water. On semiconductor chips. In brusk, we're consuming water, like food, at a rate that is completely unsustainable.

Demand for land for food is going to double – at to the lowest degree – by 2050, and triple – at to the lowest degree – past the end of this century. This means that force per unit area to clear many of the world'southward remaining tropical rainforests for human employ is going to intensify every decade, considering this is predominantly the only available land that is left for expanding agriculture at scale. Unless Siberia thaws out before we finish deforestation. By 2050, 1bn hectares of state is probable to be cleared to meet rising food demands from a growing population. This is an area greater than the Usa. And accompanying this volition exist three gigatons per twelvemonth actress COii emissions.If Siberia does thaw out before nosotros cease our deforestation, information technology would effect in a vast amount of new land being available for agriculture, as well as opening up a very rich source of minerals, metals, oil and gas. In the process this would almost certainly completely change global geopolitics. Siberia thawing would turn Russia into a remarkable economic and political force this century because of its newly uncovered mineral, agricultural and free energy resource. Information technology would also inevitably be accompanied by vast stores of methane – currently sealed nether the Siberian permafrost tundra – being released, greatly accelerating our climate trouble even further.

Meanwhile, another 3 billion people are going to need somewhere to alive. By 2050, 70% of the states are going to be living in cities. This century volition run into the rapid expansion of cities, also equally the emergence of entirely new cities that do not yet exist. It'due south worth mentioning that of the 19 Brazilian cities that accept doubled in population in the past decade, x are in the Amazon. All this is going to utilize yet more than land.

We currently have no known means of being able to feed x billion of the states at our current rate of consumption and with our current agricultural system. Indeed, merely to feed ourselves in the side by side 40 years, nosotros volition demand to produce more food than the entire agricultural output of the past ten,000 years combined. Yet food productivity is set to reject, possibly very sharply, over the coming decades due to: climatic change; soil deposition and desertification – both of which are increasing rapidly in many parts of the world; and water stress. By the end of this century, large parts of the planet will non take any usable h2o.

At the same time, the global aircraft and airline sectors are projected to continue to expand apace every yr, transporting more of united states, and more of the stuff nosotros desire to consume, around the planet year on year. That is going to cause enormous problems for united states in terms of more than COii emissions, more blackness carbon, and more pollution from mining and processing to make all this stuff.

But think almost this. In transporting the states and our stuff all over the planet, we are also creating a highly efficient network for the global spread of potentially catastrophic diseases. At that place was a global pandemic only 95 years ago – the Spanish flu pandemic, which is now estimated to accept killed upwards to 100 1000000 people. And that'southward before one of our more than questionable innovations – the budget airline – was invented. The combination of millions of people travelling around the world every day, plus millions more people living in extremely close proximity to pigs and poultry – ofttimes in the aforementioned room, making a new virus jumping the species barrier more likely – means we are increasing, significantly, the probability of a new global pandemic. So no wonder then that epidemiologists increasingly agree that a new global pandemic is now a thing of "when" not "if".

We are going to have to triple – at least – energy product by the end of this century to run into expected demand. To see that need, we will need to build, roughly speaking, something like: one,800 of the world's largest dams, or 23,000 nuclear power stations, 14m wind turbines, 36bn solar panels, or just go along going with predominantly oil, coal and gas – and build the 36,000 new power stations that means we volition need.Our existing oil, coal and gas reserves lone are worth trillions of dollars. Are governments and the globe'due south major oil, coal and gas companies – some of the nigh influential corporations on Earth – really going to decide to leave the money in the ground, as demand for free energy increases relentlessly? I doubtfulness it.

Meanwhile the emerging climate trouble is on an entirely different scale. The problem is that we may well be heading towards a number of critical "tipping points" in the global climate system. There is a politically agreed global target – driven by the Intergovernmental Panel on Climate Change (IPCC) – to limit the global average temperature ascent to 2C. The rationale for this target is that a rise above 2C carries a significant hazard of catastrophic climate change that would almost certainly lead to irreversible planetary "tipping points", caused by events such as the melting of the Greenland ice shelf, the release of frozen methane deposits from Arctic tundra, or dieback of the Amazon. In fact, the outset two are happening at present – at below the 2C threshold.

Equally for the 3rd, we're non waiting for climate change to do this: we're doing it right now through deforestation. And recent research shows that nosotros look certain to be heading for a larger rise in global average temperatures than 2C – a far larger rise. Information technology is now very likely that we are looking at a time to come global boilerplate rise of 4C – and nosotros can't rule out a ascent of 6C. This will be admittedly catastrophic. It will lead to runaway climatic change, capable of tipping the planet into an entirely different state, rapidly. Earth will become a hellhole. In the decades along the way, we volition witness unprecedented extremes in weather, fires, floods, heatwaves, loss of crops and forests, water stress and catastrophic bounding main-level rises. Large parts of Africa will go permanent disaster areas. The Amazon could be turned into savannah or even desert. And the unabridged agronomical system will be faced with an unprecedented threat.

More "fortunate" countries, such as the United kingdom of great britain and northern ireland, the United states and most of Europe, may well await similar something approaching militarised countries, with heavily defended border controls designed to forestall millions of people from entering, people who are on the move because their own country is no longer habitable, or has insufficient water or nutrient, or is experiencing conflict over increasingly scarce resource. These people will be "climate migrants". The term "climate migrants" is one we volition increasingly have to go used to. Indeed, anyone who thinks that the emerging global state of affairs does not have slap-up potential for civil and international conflict is deluding themselves. Information technology is no coincidence that near every scientific conference that I become to about climate change now has a new type of attendee: the war machine.

Every which way you await at it, a planet of 10 billion looks like a nightmare. What, then, are our options?

The only solution left to us is to change our behaviour, radically and globally, on every level. In short, we urgently need to eat less. A lot less. Radically less. And we need to conserve more. A lot more. To accomplish such a radical alter in behaviour would also demand radical government action. Merely as far as this kind of change is concerned, politicians are currently role of the problem, not role of the solution, because the decisions that demand to be taken to implement pregnant behaviour alter inevitably make politicians very unpopular – as they are all likewise enlightened.

So what politicians have opted for instead is failed diplomacy. For example: The UN Framework Convention on Climate change, whose task it has been for 20 years to ensure the stabilisation of greenhouse gases in the Globe'due south atmosphere: Failed. The UN Convention to Combat Desertification, whose job it's been for 20 years to stop land degrading and becoming desert: Failed. The Convention on Biological Diversity, whose task it's been for 20 years to reduce the charge per unit of biodiversity loss: Failed. Those are only iii examples of failed global initiatives. The listing is a depressingly long one. And the way governments justify this level of inaction is by exploiting public stance and scientific uncertainty. It used to be a instance of, "We demand to look for science to prove climate change is happening". This is now beyond doubt. So now it'due south, "We need to await for scientists to exist able to tell us what the impact volition be and the costs". And, "We need to wait for public stance to get backside action". But climate models volition never be costless from uncertainties. And as for public opinion, politicians feel remarkably free to ignore it when it suits them – wars, bankers' bonuses and healthcare reforms, to give just iii examples.

What politicians and governments say about their commitment to tackling climate change is completely different from what they are doing nearly it.

What most business? In 2008 a group of highly respected economists and scientists led by Pavan Sukhdev, then a senior Deutsche Bank economist, conducted an authoritative economical analysis of the value of biodiversity. Their conclusion? The price of the business organization activities of the world'due south 3,000 largest corporations in loss or damage to nature and the environs now stands at $2.2tn per year. And ascent. These costs will accept to exist paid for in the future. By your children and your grandchildren. To quote Sukhdev: "The rules of concern urgently need to be changed, so corporations compete on the basis of innovation, resources conservation and satisfaction of multiple stakeholder demands, rather than on the basis of who is well-nigh effective in influencing government regulation, avoiding taxes and obtaining subsidies for harmful activities to maximise the return for shareholders." Practice I think that will happen? No. What almost us?

I confess I used to discover it amusing, just I am at present ill of reading in the weekend papers about some celebrity proverb, "I gave up my 4×iv and at present I've bought a Prius. Aren't I doing my bit for the environment?" They are non doing their bit for the environment. But it's non their fault. The fact is that they – we – are not beingness well informed. And that'south part of the problem. We're not getting the information we need. The scale and the nature of the problem is simply non beingness communicated to u.s.a.. And when nosotros are brash to do something, it barely makes a dent in the problem. Hither are some of the changes we've been asked to make recently, by celebrities who like to pronounce on this sort of thing, and by governments, who should know better than to give out this kind of nonsense every bit 'solutions': Switch off your mobile phone charger; wee in the shower (my favourite); buy an electrical car (no, don't); use 2 sheets of loo roll rather than three. All of these are token gestures that miss the fundamental fact that the scale and nature of the problems we confront are immense, unprecedented and possibly unsolvable.

The behavioural changes that are required of us are so fundamental that no i wants to make them. What are they? We need to swallow less. A lot less. Less nutrient, less energy, less stuff. Fewer cars, electrical cars, cotton T-shirts, laptops, mobile telephone upgrades. Far fewer.And here information technology is worth pointing out that "we" refers to the people who live in the due west and the north of the world. There are currently almost 3 billion people in the globe who urgently need to swallow more than: more water, more than nutrient, more energy. Saying "Don't accept children" is utterly ridiculous. It contradicts every genetically coded slice of information we contain, and ane of the most important (and fun) impulses we have. That said, the worst thing we tin keep to do – globally – is have children at the current rate. If the electric current global rate of reproduction continues, by the end of this century at that place volition non be x billion of us. According to the Un, Zambia's population is projected to increase by 941% by the stop of this century. The population of Nigeria is projected to grow past 349% – to 730 one thousand thousand people.

Afghanistan by 242%.

Autonomous Republic of Congo 213%.

Gambia by 242%.

Guatemala by 369%.

Republic of iraq by 344%.

Kenya by 284%.

Liberia by 300%.

Malawi by 741%.

Mali by 408%.

Niger by 766%.

Somalia by 663%.

Uganda by 396%.

Republic of yemen by 299%.

Even the United States' population is projected to grow past 54% past 2100, from 315 meg in 2012 to 478 million. I do just desire to point out that if the electric current global rate of reproduction continues, past the cease of this century at that place volition not be x billion of u.s.a. – there volition be 28 billion of united states of america.

Where does this leave united states? Permit'southward look at it like this. If we discovered tomorrow that there was an asteroid on a collision grade with Earth and – because physics is a fairly simple science – we were able to calculate that it was going to hitting Earth on 3 June 2072, and we knew that its impact was going to wipe out seventy% of all life on Earth, governments worldwide would align the entire planet into unprecedented activity. Every scientist, engineer, university and business organization would be enlisted: half to find a way of stopping it, the other half to notice a way for our species to survive and rebuild if the first choice proved unsuccessful. Nosotros are in well-nigh precisely that state of affairs now, except that in that location isn't a specific appointment and there isn't an asteroid. The problem is us. Why are we not doing more virtually the state of affairs we're in – given the scale of the problem and the urgency needed – I simply cannot empathise. We're spending €8bn at Cern to discover evidence of a particle called the Higgs boson, which may or may not eventually explain mass and provide a partial thumbs-up for the standard model of particle physics. And Cern's physicists are keen to tell u.s. it is the biggest, near important experiment on Earth. Information technology isn't. The biggest and nearly important experiment on Earth is the 1 we're all conducting, right now, on Earth itself. Only an idiot would deny that there is a limit to how many people our Earth can support. The question is, is it seven billion (our current population), ten billion or 28 billion? I remember we've already gone past information technology. Well by information technology.

Science is essentially organised scepticism. I spend my life trying to prove my work wrong or look for alternative explanations for my results. It's called the Popperian condition of falsifiability. I promise I'm wrong. Simply the scientific discipline points to my not being wrong. We tin rightly call the state of affairs nosotros're in an unprecedented emergency. We urgently need to do – and I mean actually exercise – something radical to avert a global ending. But I don't think we will. I think we're fucked. I asked one of the near rational, brightest scientists I know – a scientist working in this area, a young scientist, a scientist in my lab – if there was just ane thing he had to do about the situation we face, what would it be? His respond? "Teach my son how to use a gun."
