Most livestock farming happens in large enclosed farms. These farms are called concentrated animal feeding operations or CAFOs. Animals are kept in close quarters and the spaces produce lots of industrial waste. CAFOs are polluting our air and water in a big way.
People who live near these farms have increased health risks. One solution to this could be that farmers change their animals diets which would in turn, reduce their emissions. They could also specially treat manure to decrease ammonia and other harmful gases. There are other solutions to this problem, but they need to be tested on a larger scale in order to make a difference.
