David Suzuki said this quote

There are some things in the world we can't change - gravity, entropy, the speed of light, and our biological nature that requires clean air, clean water, clean soil, clean energy and biodiversity for our health and well being. Protecting the biosphere should be our highest priority or else we sicken and die. Other things, like capitalism, free enterprise, the economy, currency, the market, are not forces of nature, we invented them. They are not immutable and we can change them. It makes no sense to elevate economics above the biosphere.

~ David Suzuki

We emerged out of nature, and when we die, we return to nature. We need to know there are forces impinging on us that we will never understand or control. We need to have sacred places where we go with respect, not just looking for resources or opportunity.

~ David Suzuki

The failure of world leaders to act on the critical issue of global warming is often blamed on economic considerations.

~ David Suzuki

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.

~ David Suzuki
