The book captures powerful images of the lives of stunning creatures from varying ecosystems around the globe in an effort to draw attention to their declining numbers.

Working with the chief scientist of the National Geographic Society, Dr. Jonathan Baillie, who also wrote the book's introduction, "Endangered" explores the moral dilemmas and issues human face in preserving these species and their environments.

Flach is an honorary fellow of the Royal Photographic Society, and his work focuses on animals and their interactions with humans. His previous work includes "Equus," "Dog Gods" and "More Than Human."
