The road to the future leads us smack into the wall. We simply ricochet off the alternatives that destiny offers. Our survival is no more than a question of 25, 50 or perhaps 100 years.

If we were logical, the future would be bleak, indeed. But we are more than logical. We are human beings, and we have faith, and we have hope, and we can work.

Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.

The real cure for our environmental problems is to understand that our job is to salvage Mother Nature. We are facing a formidable enemy in this field. It is the hunters... and to convince them to leave their guns on the wall is going to be very difficult.

The awareness of our environment came progressively in all countries with different outlets.

No sooner does man discover intelligence than he tries to involve it in his own stupidity.
