Slate has a great article up examining “green” birth control — and the various ways we might go about enjoying the pleasures of safe sex without wondering if we’re harming the earth at the same time. (I realize that’s probably the last thing on peoples’ minds — but hey, it’s an interesting thought!) Here’s a brief bit from the article on condoms,

What about condoms, the baby-prevention method favored by 18 percent of American women? Most condoms sold in the United States are made of biodegradable latex. However, they also contain preservatives and hardening agents to make sure the rubber can withstand a fair amount of friction. Those additives also make it harder for the condoms to break down in the landfill. Lambskin condoms are biodegradable, but chemical additives may inhibit the process. Naturalamb, the only widely available animal-based brand in the United States, does lubricate the lamb intestines they import from New Zealand, so it’s unclear just how easily its product breaks down. Natural condoms, however, are still likely to be a greener choice than latex condoms, and are equally as effective at preventing pregnancy. (Polyurethane condoms, which make up about 3 percent to 4 percent of U.S. sales, won’t break down at all.)
