Salmon are more than just a commodity; they are an integral part of West Coast ecosystems and culture. They provide food for marine predators and bears, eagles, and other animals along the rivers and lakes where they spawn.

The main difference between now and then is that now we are fuelling the current change, whereas 56 million years ago, it was a natural phenomenon -- although scientists are still not entirely sure what caused it.

Why does our economic system place a higher value on disposable and often unnecessary goods than on the things like clean air and productive soil? Sure, there's some contradiction in protesters carrying iPhones while railing against the consumer system. But this is not just about making personal sacrifices

Ezra Levant acknowledges that exploiting and using fossil fuels has environmental impacts. Does that mean there is a hierarchy of ethical practices or that one ethical practice cancels out other unethical activities?

I'm happy that my children have also grown up with a love for the natural world, inspired by time spent at the beach or in the mountains, and that their children are learning the same lessons. After all, people will not care as much about, or work to protect, something with which they feel no connection.

Although advances in modern agriculture have brought millions of hectares of once-unsuitable scrub land into food production, the environmental consequences of our growing "foodprint" have been severe.

One endangered herd in Alberta's tar sands region is at great risk of disappearing. Clear-cutting and no-holds-barred oil and gas exploration and development have affected more than 60 per cent of the habitat of the Red Earth caribou herd, leaving little undisturbed forest where it can feed, breed, and roam.

People accuse me and other environmentalists and scientists of being "alarmist". But the situation is alarming, and it's even more alarming that some people ignore it. This disconnect with reality is because industrial interests spend billions of dollars continually promoting discredited theories.

The spread of invasive species, overexploitation of natural resources, pollution, and climate change are also major contributors to what some scientists are calling the sixth great extinction.

One of the first lessons I learned from First Nations communities was about the importance of respect. Without respect for each other, we don't listen and we fail to learn. But respect should extend beyond our fellow humans, to all the green things that capture the sun's energy and power the rest of life on Earth.

Science is playing second fiddle to political concerns in Canada and the U.S. Recently, we've seen more "muzzling" of scientists, funding cuts, and an increasing disregard for science in policy-making. This scientific antipathy could not come at a worse time.

In some European cities, planners are finding that making life more difficult for drivers while providing incentives for people to take transit, walk, or cycle creates numerous benefits, from reducing pollution and smog-related health problems to cutting greenhouse gas emissions and making cities safer and friendlier.

Tim DeChristopher's ordeal exposes the massive power of the fossil fuel industry. Governments, including the U.S. and Canada's, often do far more to promote the interests of this industry than to protect people's rights and health.

For 32 years, my family has looked forward to our annual trip toward the Okanagan Valley to pick cherries. Now, much of that land has been converted to accommodate big houses. We have to make sure we don't sacrifice the very things that made a community attractive in the first place.

The real solutions to climate change lie with conservation and renewable energy, but because natural gas will be with us for the foreseeable future, we must do all we can to clean up practices associated with it.

Let's stop wasting our time on deniers. It would be better spent trying to resolve the serious problems we have created.

With the world facing ever-growing negative consequences of burning fossil fuels, we must weigh our options. In doing so, wind power comes out ahead. However, a backlash has been growing in many places where wind power is being developed.

Instead of respecting oceans as a life-giving miracle, we often use them as vast garbage dumps and as stores with shelves that never go empty. The shelves are going empty, though. Humans are changing the chemistry and ecology of the ocean at a scale and rate not previously believed possible.

Reports about floods and droughts and sea ice and climate change get sandwiched between clips about scandals and celebrities, and so we view them as isolated events. An environmental perspective would consider the possibility that many of the events are connected to an underlying cause.

Small-scale farming, especially using "organic" methods, is much better in terms of environmental and biodiversity impact. But is it a practical way to feed seven billion people?
