"I suspect that eradicating smallpox was wrong. It played an important part in balancing ecosystems."Keep these people talking! In fact, give 'em megaphones."The extinction of the human species may not only be inevitable but a good thing...."
"To feed a starving child is to exacerbate the world population problem."
Here's a good rule of thumb:
If the "environmentalists" are for it, oppose it. If they're against it, support it.
Somebody on a mailing list I frequent posted his rules for dealing with environmentalists and their agendas, and said it's all about the shoes:
If they're barefoot, laugh at them.
If they're wearing boots, listen.
If they're wearing wingtips, shoot 'em and run.
Works for me.
