Weighing the fundamental failure of environmentalism.

by David Suzuki

Environmentalism has failed. Over the past 50 years, environmentalists have succeeded in raising awareness, changing logging practices, stopping mega-dams and offshore drilling, and reducing greenhouse gas emissions. But we were so focused on battling opponents and seeking public support that we failed to realize these battles reflect fundamentally different ways of seeing our place in the world. And it is our deep underlying worldview that determines the way we treat our surroundings.

We have not, as a species, come to grips with the explosive events that have changed our relationship with the planet. For most of human existence, we lived as nomadic hunter-gatherers whose impact on nature could be absorbed by the resilience of the biosphere. Even after the Agricultural Revolution 10,000 years ago, farming continued to dominate our lives. We cared for nature. People who live close to the land understand that seasons, climate, weather, pollinating insects, and plants are critical to our well-being.

Environmental rules should be better, not easier.

by David Suzuki

Few people would argue against making environmental review processes and regulations more efficient – as long as they’re effective. But changes announced in the recent federal budget don’t do that. Instead, they make it easier for the federal government and industry to push through projects that could harm the environment and the economy, and limit the ability of ordinary Canadian citizens to have a say in matters of national importance.

Gulf of St Lawrence is important to Canadian identity.

by David Suzuki

 

We Canadians love the wilderness. Whether we're talking to visitors here or people we meet in our travels, our conversations almost always end up about our great outdoors and pristine natural spaces. Caring about the environment is one of the ways we define ourselves.

But how good are we at protecting what's at the core of our identity?

Religious right's rejection of science is baffling.

by David Suzuki

Is the world getting nuttier? Looking at recent events in North America, it's hard not to conclude that humanity is taking a crazy step backwards. I recall a time when science and scientists were taken seriously — but lately they've been getting knocked around, especially in the US and Canada.

The State of Tennessee, for example, passed a law that allows teachers who don't believe in evolution or human-caused climate change to challenge existing scientific theories. Yes, students should be encouraged to think critically and to question everything they are taught but, given the current political climate in the US, this is likely to lead to misinformation. In an infamous 1920s case, a Tennessee school teacher was tried, convicted, and fined for teaching evolution.

Dirty fuel should be consigned to the coal bin of history.

by David Suzuki

More than anything else, coal fueled the Industrial Revolution. It was, and still is, plentiful and cheap. It's also always been relatively easy to get at, especially if you don't mind sending kids into mines, endangering the lives of miners, or blasting the tops off mountains.

Coal is an 18th century fuel source, but we're still relying on it for much of our energy needs in the 21st century. Because it's so abundant and inexpensive, there's been little incentive to switch to cleaner but often more expensive sources.

Bicycling helps make cities cool.

by David Suzuki

Cities cover just two percent of the world's land area, yet they account for about 70 percent of greenhouse gas emissions. According to the United Nations, 59 percent of us now live in cities; in developing countries, 81 percent of people are urbanites. And those figures are rising every day.

Climate change denial isn’t about science, or even skepticism.

by David Suzuki

Lets' suppose the world's legitimate scientific institutions and academies, climate scientists, and most of the world's governments are wrong.

Maybe, as some people have argued, they're involved in a massive conspiracy to impose a socialist world order. Maybe the money's just too damn good. It doesn't matter. Let's just imagine they're wrong, and that the polar ice caps aren't melting and the climate isn't changing. Or, if you prefer, that it's happening, but that it's a natural occurrence — nothing to do with seven billion people spewing carbon dioxide and other pollutants into the atmosphere.

 

It's all about protecting corporate profits and interests.

 

Would it still make sense to continue rapidly burning the world's diminishing supply of fossil fuels? Does it mean we shouldn't worry about pollution?

We could pretend global warming isn't happening, or that humans aren't a factor if it is. That would be crazy in the face of overwhelming evidence to the contrary, but even if it weren't, there would still be no reason to continue down the road we're on. Energy is at the heart of modern society's needs, but when the source is finite, it seems folly to be hell-bent on using it up in a few generations, leaving the problems of depletion and pollution to our children and grandchildren. The longer we delay implementing solutions to our energy challenges the more costly and difficult it will be when we have to face the inevitable.

So, why do so many people insist that we remain stuck with outdated and destructive systems and technologies? Why do so many try to throw roadblocks in the way of progress and solutions? And what can we do about it?

Many books and studies have addressed the first two questions, including Merchants of Doubt by Naomi Oreskes and Erik Conway, and Climate Cover-Up, by James Hoggan and Richard Littlemore. Those show that huge sums of corporate money have been spent on campaigns to sow doubt and confusion about issues ranging from the dangers of smoking to threats to the ozone layer to climate change. It's all about protecting corporate profits and interests. That doesn't explain why so many ordinary people buy the industry spin, but a number of theories have attempted to shed light on that phenomenon.

What's important, though, is for those of us who rely on facts rather than spin to look at solutions. We can all do much more to reduce our environmental footprints, but the problem has grown so much that large-scale efforts are needed, and many of these must come from decision-makers in industry, government, and academia. However, there appears to be reluctance in some of those circles to act unless the public demands it. And so it's up to all of us to become informed. Then we can hold our leaders to account and challenge those who refuse to see the big picture.

This public responsibility is especially important in light of stepped-up efforts to deny the reality of climate change or the role humans play in it. Cases in point are illustrated by the "denialgate" scandal revealed by the release of Heartland Institute documents and the revelation that Ottawa's Carleton University hired Tom Harris, a PR man for a number of "astroturf" groups with a mechanical engineering background, to teach a course on climate change.

There are many credible sources of information, and they aren't blog sites run by weathermen like Anthony Watts or industry-funded fake science organizations. One place to start is at skepticalscience.com. Click on the tab that says "Arguments" for scientific responses to all the main climate change denier talking points.

Another great rebuttal to the deniers came in a recent article in the New York Review of Books by Yale University economics professor William D Nordhaus. He said his article, "Why the Global Warming Skeptics Are Wrong", was "primarily designed to correct their misleading description of my own research; but it also is directed more broadly at their attempt to discredit scientists and scientific research on climate change."

The misrepresentation of Nordhaus's research is typical of the Orwellian doublespeak deniers employ. Scientists and researchers are calling them on it.

Armed with credible information, we can challenge those who misrepresent science and spread confusion. If nothing else, we'll be able to breathe easier!
