David Suzuki

We are a part of nature, not apart from it. When we damage nature, we damage ourselves.

The way we see the world shapes the way we treat it. If we see the world as a machine, we treat it like one. If we see the world as a living organism, we treat it with respect.

The environment is everything that isn't me.

We have to recognize that we are part of the ecosystem, and we have to live within its limits.

The ultimate test of man's conscience may be his willingness to sacrifice something today for future generations whose words of thanks will not be heard.

Science is a way of knowing, but it's not the only way of knowing.

We are living in an age of ecological crisis, and we need to act now.

The economy is a wholly owned subsidiary of the environment.

Every breath we take, every drop of water we drink, every bite of food we eat, comes from nature.

We have to stop thinking of ourselves as separate from nature, and start thinking of ourselves as part of nature.

The greatest challenge facing humanity is to live sustainably on this planet.

We are all connected. What happens to one part of the planet affects all of us.

The future of humanity depends on our ability to live in harmony with nature.

We have to change our values. We have to put the environment first.

The most important thing we can do is to educate ourselves and others about the environmental crisis.

We are not going to solve the environmental crisis by doing more of the same.

The natural world is a source of wonder and inspiration. We need to protect it.

We have to move beyond anthropocentrism and recognize the intrinsic value of all life.

The environmental movement is not just about saving trees and polar bears. It's about saving ourselves.

We need to create a society that is based on ecological principles, not economic growth.
