The documentary Cowspiracy highlights that the main source of air pollution does not come from things such as cars or planes. Instead the main source of air pollution comes from farms.
The report out today confirms that the main source of air pollution, by far, comes from farms. The report is published in Geophysical Research Letters.
The report not only points out how farming emissions are causing air pollution. It also points out that 'increased' use of fertilization and meat production is threatening ecosystems.
Therefore, the conclusion of this study finds that farming practices are harming the environment and harming the natural world.
