One of the most surprising things we unearthed while researching the little green guide was that eating less red meat is one of the best ways to reduce your contribution to global warming. Meat production means clearing forest, and there are a lot of fossil fuel inputs into growing feed and so on. Cows also produce a lot of methane, another climate change gas. In fact reducing your red meat intact will save more CO2 emissions than trading your car in for a hybrid. And it’s a lot cheaper too.
