What are examples of human causes of animal extinction?

Answer 1

Though we generally name only a few organisms as becoming extinct in recent times, there are actually hundreds of them: causes of extinction in all cases are habitat destruction or hunting: by MAN.

I have selected few examples randomly, there are many:

Extinction caused by invasion of man and his pets, parasites in an island: duck-like Moa-nalo birds from Hawaii about thousand years ago, flightless giant birds called Moa from New Zealand about 600 years ago, flightless bird Dodo from Mauritius 500 years ago, giant tortoise of Pinta island , a subspecies of Galapagos tortoise in twentieth century.

Extinction caused due to hunting by Europeans and local rulers: Indian Cheetah, Caspian Tigers, Syrian Elephants .

Extinctin caused by rapid loss of habitat due to urbanisation and spread of agricultural lands, along with hunting: Passenger pigeons of North America.
