Australians really don't like the hundreds of thousands of feral camels that run around the continent, so every once in a while the government decides to spend money on sending guys with guns up in helicopters to cull their numbers. But now they have a utilitarian justification for the culls: They're fighting climate change.
Like cows, camels spew methane from their digestives systems. By cutting their lives short, one company argues, Australia would be preventing the release of the methane the camels would emit over their remaining years. The company, Northwest Carbon, also says it'll be able to offer carbon credits for the reduction in emissions.
The camels are only in Australia to begin with because they were imported there in the 19th century for transport needs. But now, they’re useless and for the greater good they need to be disappeared, apparently.
