Species loss has been cited as a problem in the DRC, brought about or exacerbated by reasons that include deforestation for mining, wood fuel, infrastructure or agriculture, war, illegal poaching and increased consumption of bush meat due to overpopulation and lack of food security. Some attempts to combat species loss in countries such as the DRC are actions such as the UN's Sustainable Development Goals (SDG), specifically SDG 15 Life on Land, the primary goals of which is to increase reforestation and biodiversity and reduce species loss, desertification, and illegal poaching. One of the primary defences for species and habitat protection in the DRC is its system of national parks and reserves, which gives protected status to nearly 12% of the DRC's rainforest. Five of these parks and reserves are UNESCO world heritage sites, including Africa's first national park Virunga national park. All of these parks have been put on the World Heritage in Danger List. Poor governance and low economic conditions have reduced the effectiveness of these protections, especially during war times. The human cost of protecting these parks has also been high with 200 park ranger deaths in the past 20 years. Virunga national park and Salongo National Park, both of which are UNESCO world heritage sites are currently being looked at for mining and oil exploration. The move would open 21.5% of the Virunga park for exploitation, this is highly criticised by animal rights activists as it would threaten the habitat of mountain gorillas and other endangered species.
