Environmental groups in the Democratic Republic of Congo are warning that gold mining in the northeast of the country is threatening the habitat of the forest giraffe. The stripy-legged herbivore which is the only living relative of the more familiar giraffe is already considered an endangered species. The BBC quotes organisations, including the Congolese Alert Network for the Environment and Human Rights, as saying that mining operations in the Okapi Wildlife Reserve, a Unesco World Heritage Site are expanding, despite an official ban on their activities.
