In the environmental movement, every time you lose a battle it's for good, but our victories always seem to be temporary and we keep fighting them over and over again.

Education has failed in a very serious way to convey the most important lesson science can teach: skepticism.

The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continents are interconnected. That is our home.

The voluntary approach to corporate social responsibility has failed in many cases.

In the environmental movement, every time you lose a battle it's for good, but our victories always seem to be temporary and we keep fighting them over and over again.

Our personal consumer choices have ecological, social, and spiritual consequences. It is time to re-examine some of our deeply held notions that underlie our lifestyles.

We're in a giant car heading towards a brick wall and everyone's arguing over where they're going to sit.

It's time we stopped ignoring the environment. Let's not let another election go by without making this a high priority.

We must reinvent a future free of blinders so that we can choose from real options.

All those hours exploring the great outdoors made me more resilient and confident.

Although it's difficult, if not impossible, to put a dollar value on the numerous services nature provides, leaving them out of economic calculations means they are often ignored.

Although it's the second largest country in the world, our useful area has been reduced. Our immigration policy is disgusting: We plunder southern countries by depriving them of future leaders, and we want to increase our population to support economic growth.

As parents, grandparents, uncles and aunts we need to start getting out into nature with the young people in our lives. Families play a key role in getting kids outside.

Because countries often have differing political and economic systems, agreements are needed to protect those invested in trade.

Being an environmentalist isn't all about doom and gloom.

Beyond reducing individual use, one of our top priorities must be to move from fossil fuels to energy that has fewer detrimental effects on water supplies and fewer environmental impacts overall.

Birds are, especially canaries, are super sensitive to hydrogen sulfide and sour gas.

Canada should always open its doors to those who are oppressed or in cases of emergency. When Canada offered refuge to 50,000 boat people in Vietnam in the 1970s, I was particularly proud to be Canadian.

Change is never easy, and it often creates discord, but when people come together for the good of humanity and the Earth, we can accomplish great things.

Conserving energy and thus saving money, reducing consumption of unnecessary products and packaging and shifting to a clean-energy economy would likely hurt the bottom line of polluting industries, but would undoubtedly have positive effects for most of us.

Corporations are economic entities or structures, and yet they're allowed to fund political candidates, and when those candidates are elected, guess who gets in the door first? It's corporations.

Corporations are not people. They shouldn't be funding. They shouldn't be funding campaigns at all.

Do you know how much land is under ice, rock and snow? Do you know why 90 percent of us live within 100 kilometres of the U.S. border? We have this idea we're a vast country. But the reality is that a lot of it, a huge amount, is uninhabitable.

Doing all we can to combat climate change comes with numerous benefits, from reducing pollution and associated health care costs to strengthening and diversifying the economy by shifting to renewable energy, among other measures.

Environmentalism has failed.

Environmentalism isn't a discipline or specialty. It's a way of seeing our place in the world. And we need everybody to see the world that way. Don't think 'In order to make a difference I have to become an environmentalist.'

Exxon, one of the companies that has spent tens of millions of dollars denying climate change, denying any responsibility to deal with, taking government subsidies on a massive scale, now their ads are all about, 'Oh, we want a clean future. We're looking at clean energy and all that stuff.'

Faced with the evidence, many deniers have started to admit that global warming is real, but argue that humans have little or nothing to do with it.

Feeding our energy appetite is top of mind for many people these days.

For the sake of our health, our children and grandchildren and even our economic well-being, we must make protecting the planet our top priority.

From year to year, environmental changes are incremental and often barely register in our lives, but from evolutionary or geological perspectives, what is happening is explosive change.

Geothermal can be a huge source of energy very quickly.

Global trade has advantages. For starters, it allows those of us who live through winter to eat fresh produce year-round. And it provides economic benefits to farmers who grow that food.

Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges.

Humans are distinguished from other species by a massive brain that enables us to imagine a future and influence it by what we do in the present. By using experience, knowledge and insight, our ancestors recognized they could anticipate dangers and opportunities and take steps to exploit advantages and avoid hazards.

Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater, as well as accidental spills, can contaminate drinking water and harm human health.

I can't imagine anything more important than air, water, soil, energy and biodiversity. These are the things that keep us alive.

I feel humiliated that I live in a country that demands more already. Why do we cling to the notion that not only must we maintain the current level of consumption, but that it must continue to grow by an exponential factor of 2 to 7 percent every year?

I fell in love with the elegance and precision of genetic analysis and experimentation to answer profound biological questions.

I read in 'Life' magazine that Asians had developed an operation to enlarge eyes, and I yearned to have this done. I wanted to dye my hair brown and to anglicize my name. Self-hate was the most terrible cost of the war years for me.

I've always been more interested in organisms that can move on their own than in stationary plants. But when I canoe or hike along the edge of lakes or oceans and see trees that seem to be growing out of rock faces, I am blown away. How do they do it?

If America wants to retain its position as a global power, its president must listen to the people and show strong leadership at this turning point in human history.

If we have any hope of finding ways for seven billion people to live well on planet with finite resources, we have to learn to use our resources efficiently. Plastic bags are neither efficient nor environmentally friendly.

If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

If we want to address global warming, along with the other environmental problems associated with our continued rush to burn our precious fossil fuels as quickly as possible, we must learn to use our resources more wisely, kick our addiction, and quickly start turning to sources of energy that have fewer negative impacts.

If you're not being pessimistic, you're not being very realistic. But I think one must always have hope, and when you have children, of course, you have no choice but to work your tail off to try and protect the future for your children. And that is infused by hope in the end.

It's not unexpected that shooting massive amounts of water, sand, and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren't the worst problem with fracking.

Japan is a model already to the lie that economic growth is the key to our future. If they can really show an alternative to nukes and fossil fuels, then they will be the poster boy for the renewable energy for the future.

Japanese people cut their energy use by 25 percent immediately after Fukushima. They showed there was huge opportunity there. And instead, the government simply wants to get those plants up and running again.
