I firmly believe that we can have a healthy environment and a sustainable timber industry.

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

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

Unless we keep this planet healthy, everything else is for naught.

People blame their environment. There is only one person to blame - and only one - themselves.

Unless we keep this planet healthy, everything else is for naught.

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

Harmony with land is like harmony with a friend you cannot cherish his right hand and chop off his left.

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.

The only way forward, if we are going to improve the quality of the environment, is to get everybody involved.
