Everyone loves food, and the good news is that enjoying the right sorts of food can help keep the planet cool. The right sort (sorry burger lovers) is definitely not cows- who have problems with gas emitted from their, ahem, nether regions. We are not just talking the occasional accidental and slightly embarrassing emission. If cows were their own Nation they would be the third largest emitter of greenhouse gasses after the USA and China!!! Not Amoosing.
