I know that war and mayhem run in our blood. I refuse to believe that they must dominate our lives. We humans are animals, too, but animals with amazing powers of rationality, morality, society. We can use our strength and courage not to savage each other, but to defend our highest purposes.

Relative to most of the energy and material flows on Earth, the machinations of humankind are puny. The planet's powers are much, much bigger than our own. But in a few sensitive places, we're making an impact on a planetary scale, and that impact is not a good one.

There is hardly a place on Earth where people do not log, pave, spray, drain, flood, graze, fish, plow, burn, drill, spill or dump. There is no life zone, with the possible exception of the deep ocean, that we are not degrading.

We know it is impossible to go on finding, moving and wasting oil, leveling forests, paving land, dumping poisons, and multiplying our numbers. A new way of life, a new set of thoughts must be found.
