There’s a cool new video on “conservation biology,” which you can find here. It has fabulous photos, as well as interesting commentary on the role of photography in prompting conservation.
The photo to the left is an early example: a 19th century shot of Yellowstone that helped prompt the creation of the national park there. The photographer, William Henry Jackson, was an important 19th century photographer and painter who died at the age of 99 in 1942. BYU has a great collection of his photos.
