I would encourage anyone who is concerned about the environment – and, indeed, involved in environmental causes – to take a look at this (pdf) history of the environmental movement called "Hysteria’s History".
When taken as a whole, there are some particularly damning items for which the Green Movement has never been held accountable. The consequences of some green regulations have gone from counterproductive to genocidal. Tough language to be sure. But see for yourself.
(See also this piece on ozone, which has ominous parallels with today’s global warming hysteria.)
