> Has this guy not heard of the Bengal tigers of the Sundarban forests, which kill ~50 humans per year?

How many tigers have been killed by humans? How many would be killed if humans did not restrain each other from killing tigers because we have killed so many that they are endangered. That population could be entirely wiped out by humans in the area.

Mosquitoes kill far more people than tigers. So do venomous snakes. The fact is that when a human faces either of these they are far more likely to end up dead than the human.
