This depletion will cause UV to enter earth. This will cause extinction of mankind.
Hurricanes because it covers the most land.
Extinction events, such as the Permian extinction and the KT extinction event. You have adaptive radiation driving evolutionary change after such events. Google " the rise of the mammals. "
Most likely from H. heidelbergensis.
Deforestation, because most of animal species live in the rainforest but it is getting cut down so animals get closer to extinction. Like the jaguar.
Extinction
most probably change in the climatic condition was the main reason for their extinction!!
Human
Blue-fin tuna fish are really close to extinction. They are most likely have the Highest Chances Of Extinction!

Deforestation of rainforests will likely lead to extensive extinction of species.
Aspirin is the NSAID that is most likely to cause ulcers.
