Environmentalists are the limp-wristed, prius-driving, birkenstock-wearing poor excuses for human beings that see humanity as a pestilence rather than a part of our creator's universe. Most of them have no concept of valid scientific practices, rather they are "schooled" in the humanities and "junk sciences". As predicted, there are very few environmentalists in the hard sciences.
If environmentalists are so concerned about humanity destroying the earth (never happen), maybe they should be the first to give up their lives. It is easy for environmentalists to make pronouncements about what the rest of the "unwashed masses" should do . . .
