Protecting wildlife today and tomorrow

For World Wildlife Conservation Day, we're dropping in to visit a herd of African elephants in the Addo Elephant National Park in South Africa. Established in 1931 to protect a small herd of just 11 African elephants, today Addo ranks as the third-largest national park out of the 19 in South Africa and provides a safe haven for about 600 of these magnificent creatures, as well as cape buffaloes, various antelope species, lions, hyenas, and endangered black rhinos.
