Water borne illnesses are going to get worse and worse as climate change gets worse.
Not just because they always run rampant after a natural disaster like a flood or a hurricane. Although that will be a big problem as well.
But also because often parasites and bacteria are limited by the average temperatures of the climate around them. It's another reason there are so many water borne diseases in Africa.
It's already happening with trees and things. Diseases that were once killed off over the winter, giving the tree a break, now continue unstopped. The poor tree eventually dies.
We need to wise up and do something about climate change before it's too late.
