Causes of Global Warming | WWF-Australia - WWF-Australia

When livestock are grazed at a large scale, as in Australia, the amount of methane produced is a big contributor to global warming. Some fertilisers that farmers use also release nitrous oxide, which is another greenhouse gas. Australian farming contributes 16% of our total greenhouse gas emissions.
