Important for keeping planet warm: concentration of carbon dioxide is directly proportional to greenhouse gas, process affecting greenhouse gases. Health effects of climate change: not known for sure. Ozone depletion: not really holes in the ozone; the layer is thinning due to release of cfcs, bad uvs; uva and uvb; reach ground and affect humans and other living organisms, dramatic increase in dermal cancer. Species loss: since the discovery of fire, there has been large impacts with other species, never been as big since the industrial revolution. If species is gone, it is gone forever; biggest loss of all; caused by humans: wetlands have dried out.
