Poaching is a huge problem in Africa. It doesn't just include elephants, lowland gorillas are also poached but elephants poaching is also a big problem. The poachers want the tusk of the elephant which can sell for thousands.
Apartheid started after the end of the Berlin conference when Europe owned a large portion of Africa so there were many european living in Africa. They believed that the uncolored race was superior to the colored race so they treated the actual native africans like trash. So it's pretty much like segregation in the U.S. but worse.
BLACK TO THE BACK
The Berlin Conference in 1884 was when the main dominating forces in Europe came together and split the land in Africa. The Europeans conquered the land of the Africans and moved the africans to a overpopulated and terrible land somewhere far from their home whether they like it or not.
