Did you know that there are currently 41,415 endangered species on our planet? Of those, 16,306 species are extremely endangered and on the brink of extinction – roughly 30% of those endangered animals.

Sadly, most of this is due to humans. Destroying of land, poaching, and over-fishing or hunting have caused these animals to slowly dwindle in numbers.

One photographer named Tim Flach made it a mission to travel the world and photograph some of these majestic creatures before they’re gone forever. In his book, Endangered, he has documented many of these incredible animals.

These are 40 of his most gorgeous and heartbreaking photos.
