It's from love and knowledge of nature that any sensible understanding must come. Technology is essentially antagonistic to nature - that in fact is why it's created, to do something to or with nature that wasn't there before, that wasn't natural.

So the technology that does the least alteration of nature, the least harm to other species and systems, and provides the greatest intimacy of human with nature, is the best. We could make a scale with that in mind, and judge any technology by its place on that scale: speech and eyeglasses, say, would rank low; nuclear bombs and coal plants, high.

I'm convinced that the catastrophes of the next two decades will be so vast as to bring about a world where life, if it survives, will be far simpler - and the technologies, too. Then we will have come full circle to something like life on the savanna.

That is the onslaught. It has been going on a long time, I argue, but in the 20th century humans have certainly perfected it, extending domination to every single corner of the earth and our Homo sapiens population to more than 6 billion - until no place is untouched by despoliation.

It's from love and knowledge of nature that any sensible understanding must come. Technology is essentially antagonistic to nature - that in fact is why it's created, to do something to or with nature that wasn't there before, that wasn't natural.

Economic and social misery increases in direct proportion to the size and power of the central government of a nation or state.

I want to leave my country without leaving my home.
