The Elephants and Rare White Rhinos of Garamba National Park, Democratic Republic of Congo

What you'll see: The park became well-known in the 1930s when it created an African elephant domestication program, in which these animals were trained for use in forestry and tourism.

Why it's in danger: Since then, the elephant population has fallen to just 4%. The park was also home to the only remaining white rhinos in the world, but it's believed they'll soon go extinct due to poaching and civil unrest in the area.
