His book RARE: Portraits of America's Endangered Species features portraits of some of the country's most endangered species. "Some of them are likely to go extinct without people ever knowing they existed. Rare shows what we stand to lose if we don’t act now. The good news is that there is still time, and this book highlights what each of us can do to save these unique creatures —and ultimately ourselves."
