It’s Getting Hot and Crowded on This Rock

The United Nations, which tracks world population growth, has upped its estimates. We know that we’ll pass the seven billion mark sometime this October, but the U.N. is now saying we could hit 10 billion within the century – nearly a billion more than expected. Actually, by 2050 we will likely hit 9.3 billion. For some perspective, the planet held five billion people back when Johnny Depp was just starting his career on the TV show 21 Jump Street (Yes, I admit, I was a huge fan of that show). That was the mid-1980s – not so long ago, is it?

Ten billion people are a lot of mouths to feed, bodies to hydrate and families to shelter. It translates into more vehicles on roads, more gigawatts of electricity demand, and more land needed for growing crops. And dramatically more garbage and pollution. It will become much more difficult for supply to meet this demand. Commodity prices will continue to rise, as they have been. Fresh water resources will become more scarce. Regional conflicts will grow. Greenhouse gas emissions will rise. This isn’t scaremongering, this is reality. Even climate skeptics must appreciate that the current path is unsustainable. Global warming isn’t the only reason to be concerned.

Now, reducing waste, eliminating inefficiency and doing things in a more intelligence way will help, but ultimately dealing with the planet’s population explosion will also require a complete rethinking of where we get energy and how we use it. We can’t simply “shoe-horn” renewables into an existing fossil-fuel infrastructure, at least not in the long term. We need to imagine an infrastructure that puts renewables and low-emission energy sources first, and then begin the difficult task of making the transition. Many barriers (entrenched interests, risk aversion, lack of political leadership and citizen buy-in) will need to be overcome, but what’s the alternative?

The Intergovernmental Panel on Climate Change released a short preview of an upcoming report today that asserts we can make the transition. It concludes that nearly 80 per cent of the world’s energy supply could by 2050 be met through deployment of renewable energy technologies — particularly those that capture solar energy. Now, it’s a highly optimistic scenario, but it’s what we need to help keep GHG emissions below 450 parts per million and keep the global temperature from rising beyond 2 degrees C.

Are we too intimidated by the daunting task ahead? Perhaps that’s part of the problem. The IPCC spends many years putting together a massive and comprehensive report on the climate and then plunks it down for all the world to see. It’s information overload — simply too much to digest in one sitting — and it gives the impression that we have a problem that’s too big to tackle. The IPCC’s Fourth Assessment was roughly 3,000 pages! The Fifth Assessment, currently in the works, will be an equally large tome filled with depressing conclusions and broad calls for action that no countries appear ready to embrace.

I agree with folks like Andrew Weaver from the University of Victoria, who is perhaps Canada’s top climate scientist. He says we need to start targeting the science and dividing the problem into smaller, more manageable chunks. ”The science behind the problem is so utterly solid is that what we need to do is start carving pieces off and dealing with those,” Weaver recently told me.
Take, for example, global emission from landfills, which represent up to 4 per cent of total global GHGs. Why doesn’t the IPCC come out with a full report dedicated to the problem of landfill methane emissions and how to tackle it aggressively? Another report could focus on air travel, another major contributor, or tropical deforestation, or agricultural, or even geo-engineering as an attempt to buy time for adaptation programs. “Hiving off these parts and focusing international negotiations on individual sectors is probably where we need to go,” said Weaver. “The problem is so big people don’t know where to begin, so we have to go in this direction. Some are easy to tackle, some are more difficult. All of them are doable if you deal with them bit by bit.”

Now, back to the climate skeptics. Many say Canada is so insignificant that there’s no point in taking any action that could threaten our economy. How, for example, can a country of less than 50 million really register in a world heading toward 9 billion? One can see the allure of the do-nothing position when looked at this way. The problem with this argument is that it ignores the other problems — real, verifiable problems — that come with overpopulation and rapid depletion of resources, particularly fossil fuels. Air quality. Water scarcity. Geopolitical instability. Rising oil prices. Mass immigration that threatens to overwhelm the west’s social systems. Economic volatility. Even if you forget about greenhouse gases, there are plenty of hazards ahead that should concern us. Canada is not an alone. These issues will impact us, and will take a toll on our economy and standard of living.

Moving away from increasingly expensive fossil fuels toward locally generated, zero-emission energy sources, and using clean technologies to reduce waste will enhance our economic competitiveness during these trying times. By becoming more self-sufficient, we can become more insulated from many of the global challenges that lie ahead.

Putting our eggs in the fossil fuel basket, on the other hand, greatly exposes us to these challenges. Sure, a small group of people will get really rich (and this will skew our national GDP, which is a misleading indicator of a country’s economic health). But we will become more vulnernable to the volatility of oil and gas prices, commodity price swings and other gyrations of our international markets.

 I can’t help but think that North America, at the moment, is like a teenage athlete that continues to take steroids to win a race, only to ignore the heart attack that’s likely to come at age 25. Where’s the glory in that? There’s a quote in the Coppola movie Rumble Fish, in which Rusty James asks his brother what California is like (in the 1980s). His brother answers back: “California’s like a beautiful, wild girl on heroin who’s high as a kite, thinkin’ she’s on top of the world, not knowing she’s dying even if you show her the marks.”

    I mentioned the curse of excess population in the preface or first chapter of my book SCARCITY, ENERGY AND ECONOMIC PROGRESS about 25 or 30 years ago. Some people thought that I was crazy, because one well known scholar in Australia informed me that there was room for 40 billion souls in this old world of ours. I wont call his name but his initials were C as in Colin, and another C as in Clark.Population is in fact the elephant in the closet with you. Dont tell the TV audience though, because that is something they do not want to hear, although they get the message loud and clear. Will our political masters be able to deal with this? Well, in Germany Ms Merkel and her henchment say that doing away with nuclear, and investing in something else, will give Germany a "COMPETITIVE ADVANTAGE". And the guy called ME crazy.

    As I said somewhere else, if you can't fuel transport (planes, trucks/lorries of various sorts, other four-wheel vehicles etc.)to get food from where it's grown to where it's consumed, and you can't find petroleum for plastics, everything else is pie in the sky, wishful thinking. Now this information about population explosion just confirms this fundamental notion that we seem to forget about.
