Who knew there was a Voluntary Human Extinction Movement? As long as it's voluntary, I'm all for it. I like volunteerism.
From the piece at No Left Turns:
The VHEM position is “realistic: We know we’ll never see the day there are no human beings on the planet. . . . The Movement may be considered a success each time one more of us volunteers to breed no more.” The VHEM approach demographically guarantees that its hard task will only get harder. Those non-breeding volunteers will have no children to catechize, while the people who do breed will have set an anti-VHEM example for their children simply by virtue of having them.
Instead of stigmatizing people who drive SUVs and eat beef, let's just stigmatize anyone who has kids. Better yet, the members of this movement, to be morally consistent, should simply off themselves right now, in some sort of Gaia-friendly manner. After all, breathing and farting are major sources of CO2.
