Global warming also causes animal death. Some animals, like owls, live in trees other animals, insects mostly, live on plants, on the roots, on leaves or other parts of a plant. It also affects bigger animals, like panthers, that eat deer, which eat plants. This is called a food chain and when the producer, plants, is not there to give nutrients to other animals everything dies.
Do you see the overwhelming effects of global warming? It has a very long cause and effect sequence. When humans started to make factories plant life depleted which in cause caused many years of misfortune. Animals and humans started to decimate because of malnutrition and UV radiation. This was cause by a high concentration of CO2 making a hole in the ozone.
As you can see global warming is still a very big problem that needs to be fixed.
