No one should be able to enter a wilderness by mechanical means.

The environment is everything that isn't me.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

I have a private plane. But I fly commercial when I go to environmental conferences.

We won't have a society if we destroy the environment.

When we realize we can make a buck cleaning up the environment, it will be done!

By polluting clear water with slime you will never find good drinking water.

Not all is doom and gloom. We are beginning to understand the natural world and are gaining a reverence for life - all life.

Take a course in good water and air and in the eternal youth of Nature you may renew your own. Go quietly, alone no harm will befall you.

I think the cost of energy will come down when we make this transition to renewable energy.
