I've got personal views on the '60s. You can't have freedom without paying the price for it.

We rushed into renewable energy without any thought. The schemes are largely hopelessly inefficient and unpleasant. I personally can't stand windmills at any price.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

Those of us who consider ourselves to be somehow involved in the birthing of a new age, should discover Gaia as well. The idea of Gaia may facilitate the task of converting destructive human activities to constructive and cooperative behavior. It is an idea which deeply startles us, and in the process, may help us as a species to make the necessary jump to planetary awareness.

The tropical rain forests are a telling example. Once cut down, they rarely recover. Rainfall drops, deserts spread, the climate warms.

Nowadays if you're dependent on a grant - and 99% of them are - you can't make mistakes as you won't get another one if you do.

The world has not warmed up very much since the millennium. Twelve years is a reasonable time... it (the temperature) has stayed almost constant, whereas it should have been rising - carbon dioxide is rising, no question about that.
