Protecting wildlife today and tomorrow

For World Wildlife Conservation Day, we're dropping in to visit a herd of African elephants at Addo Elephant National Park in South Africa. Established in 1931 to protect a small herd of just 11 African elephants, today Addo ranks as third largest of the 19 national parks in South Africa. It 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.
