Feeding Humanity In A Warming World

Industrial agriculture has made it possible to produce large amounts of food efficiently, but comes with problems, including pollution, reduced biodiversity, pesticide resistance and consequent increased chemical use, destruction of forests and wetlands, and human health issues such as antibiotic resistance.

Eating Less Meat Will Reduce Earth's Heat

Estimates of how much animal agriculture adds to greenhouse gases range widely, from about 14 to more than 50 per cent of total global emissions. Agriculture exacerbates climate change in a number of ways. Clearing carbon sinks such as forests to grow or raise food can result in net greenhouse gas increases. Farming, especially on an industrial scale, also requires fossil fuel-burning machinery, as does processing and transporting agricultural products.
