Actually there was a report put out by the United Nations some years ago--sometime during the second term of George Bush--and it's been suppressed or minimized, but anyway, it said that the hippies and environmentalists (it didn't exactly call them that, but heavily suggested that) were the biggest mass-murderers of the 20th century, surpassing even Mao, Stalin, Hitler, and Lenin.
The toll in the third-, fourth-, and fifth-worlds from malaria has been horrendous.
And we got the hippies and environmentalists to blame for it.
But what do they care? They feel good, and that's all that matters to them.
