Last of the Giants

This was a very interesting account of some of the largest species to ever walk the earth and how many of them are now extinct or or the verge of extinction.  Included in the list of animals are some that are not necessarily large in size but were large in impact like the passenger pigeon.  There were 13 animals highlighted in the book.  Each section talked about the animal and its habits and then how and why it became extinct or almost extinct.  Well done.
