Iain Douglas-Hamilton reflects on a lifetime studying elephants and discusses the current surge in ivory poaching.

At age 23, Iain Douglas-Hamilton pioneered the first in-depth scientific study of elephant social behavior in Tanzania's Lake Manyara National Park. During the 1970s he investigated the status of elephants throughout Africa and was the first to alert the world to the ivory poaching holocaust. He and his wife have co-authored two award-winning books and have made numerous television films. In 1993, he founded Save the Elephants, a Kenyan conservation organization dedicated specifically to elephants. In 2010, he was named the recipient of the prestigious Indianapolis Prize, in recognition for his lifetime achievements.
