What we eat can harm not only our health, but the planet itself. About a quarter of all the greenhouse gas emissions that humans generate each year come from how we feed the world. Most of them are methane released by cattle, nitrogen oxides from chemical fertilisers and carbon dioxide from the destruction of forests to grow crops or raise livestock.
