Eat Kangaroos--Save Polar Bears from Drowning!

The math goes like this. Australia is trying to figure out how to cut its emissions of greenhouse gases without crippling the economy. Cattle and sheep, by grace of their bodily functions, emit a lot of greenhouse gases—about 11% of Australia’s total emissions, and about two-thirds as much as all the cars and trucks in Australia. Kangaroos don’t, because they have a different digestive system. So if kangaroos replaced part of the cattle herds as a food source, Australia could cut its emissions by 16 million tons, or 3%, ranchers could earn hundreds of millions of dollars—and there’d still be plenty of juicy steaks.
