Large livestock farms can also serve as a source for spillover of infections from animals to people. Loss of habitat forces animals to migrate and potentially contact other animals or people and share germs. Deforestation, which occurs mostly for agricultural purposes, is the largest cause of habitat loss worldwide. Many of the root causes of climate change also increase the risk of pandemics.
