EMERGING diseases and disasters relate to climate change. As the planet heats up, animals big and small, on land and in the sea, are headed to the poles to get away from the heat. That means animals are coming into contact with other animals they normally wouldn’t, and that creates an opportunity for pathogens to get into new hosts.
Many of the root causes of climate change also increase the risk of pandemics. Deforestation, which occurs mostly for agricultural purposes, is the largest cause of habitat loss worldwide. Loss of habitats forces animals to migrate and potentially come into contact with other animals or people and share micro organisms.
