Virunga National Park is one of the most biologically diverse protected areas on the planet. Half of all the biodiversity in sub-Saharan Africa can be found in Virunga. The park is also a geologic wonder and contains two of the world's most active volcanoes. For much of its long history, though, Virunga National Park has been severely threatened by armed conflict. Thanks to the dedication of the park's rangers and wardens, Virunga has been able to survive. Certain politicians, the European Union, conservationists, philanthropists, and private donors have also played a vital role in Virunga's survival.
