My efforts in Congress are guided by the belief that environmental preservation and restoration are a critical part of the legacy we leave to future generations.

Environmental policy must strike a balance between the earth's best interests and our citizen's pressing needs.

But reducing harmful emissions, abating our dependence on foreign oil and developing alternative renewable energy sources have benefits that go beyond environmental health, they improve personal health, enhance national security and encourage our nation's economic viability.

All living beings, not just animals, but plants and microorganisms, perceive. To survive, an organic being must perceive - it must seek, or at least recognize, food and avoid environmental danger.

We have a project with Unocal here in Los Angeles, where we as an environmental organization, the oil company, and the state all get together to promote the recycling of used motor oil.

We're not trying to reinvent the wheel for any environmental organization to claim sole responsibility for any kind of victory is insane, because everybody attacks these problems as a group.

The environmental movement, like all political processes, reacts best to disasters. But these are very slow, very gradual disasters in the making.

Address these environmental issues and you will address every issue known to man. And we keep dabbling in things that aren't really that important in the long term.

Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.

I align myself with almost all researchers in assuming that anything we do is a composite of whatever genetic limitations were given to us by our parents and whatever kinds of environmental opportunities are available.
