The author of the Manifesto, Theodore J. Kaczynski, is in jail, a certified nutcase who sent mail bombs to complete strangers, killing some, injuring others who survived. The author of Earth in the Balance almost pulled off a judicial coup d'etat, a putsch, a plain, flat-out stealing of an office won by a preponderance of the vote by George W. Bush. Bush won more States, won more counties, won areas that added up to more population. Al Gore's view of the world is very different from most people. Here's a few quotes from his book.
Human civilization is now the dominant cause of change in the global environment.
Today, most of the world is looking the other way, pretending not to notice industrial civilization's terrible onslaught against the natural world. Humans and civilization are, in Gore's view, a dangerous, bad thing. And then there's the automobile. We now know that their cumulative impact on the global environment is posing a mortal threat to the security of every nation more deadly than that of any military enemy we are ever again likely to confront. What I found most disturbing throughout the campaign was the total lack of focus on Gore's environmental views by either the Bush camp and, of course, the media.
