A few weeks ago, New York Times environmental blogger Andrew Revkin made a relatively straightforward observation, that “more children equal more carbon dioxide emissions.” Revkin went on to suggest that family planning and contraception might be an important part of any plan to limit CO₂ emissions: Are Condoms the Ultimate Green Technology?

I recently raised the question of whether this means we’ll soon see a market in baby-avoidance carbon credits similar to efforts to sell CO2 credits for avoiding deforestation. This is purely a thought experiment, not a proposal. But the issue is one that is rarely discussed in climate treaty talks or in debates over United States climate legislation. If anything, the population-climate question is more pressing in the United States than in developing countries, given the high per-capita carbon dioxide emissions here and the rate of population growth. If giving women a way to limit family size is such a cheap win for emissions, why isn’t it in the mix?

This led Rush Limbaugh, on his radio show today, to compare environmentalists with suicide bombers, and suggest that Andrew Revkin should commit suicide.

LIMBAUGH: I think these militant environmentalists, these wackos, have so much in common with the jihad guys. Let me explain this. What do the jihad guys do? The jihad guys go to families under their control and they convince these families to strap explosives on who? Not them. On their kids. Grab your 3-year-old, grab your 4-year-old, grab your 6-year-old, and we’re gonna strap explosives on there, and then we’re going to send you on a bus, or we’re going to send you to a shopping center, and we’re gonna tell you when to pull the trigger, and you’re gonna blow up, and you’re gonna blow up everybody around you, and you’re gonna head up to wherever you’re going, 73 virgins are gonna be there. The little 3- or 4-year-old doesn’t have the presence of mind, so what about you? If it’s so great up there, why don’t you go? Why don’t you strap explosives on you — and their parents don’t have the guts to tell the jihad guys, “You do it! Why do you want my kid to go blow himself up?” The jihad guys will just shoot ‘em, ‘cause the jihad guys have to maintain control.

The environmentalist wackos are the same way. This guy from The New York Times, if he really thinks that humanity is destroying the planet, humanity is destroying the climate, that human beings in their natural existence are going to cause the extinction of life on Earth — Andrew Revkin. Mr. Revkin, why don’t you just go kill yourself and help the planet by dying?
