This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.
some forest are really affected by activity because polluted they put trash in the water and they never clean it up and the animal life are getting sick and they are dying this does affect diversity because animals can die if we have polluted waters
