A proposed Northern Serengeti all-weather tarmac road that will bisect Serengeti National Park, a World Heritage site, has sparked considerable debate. Opponents say that the road could disrupt the migration of approximately 1.5 million wildebeest, zebras and gazelles between Serengeti National Park and Masai Mara National Reserve in Kenya, and increase already high levels of poaching. Proponents, on the other hand, argue that the road will facilitate national and local economic growth, which in turn will reduce poverty and improve the local quality of life, which is expected to lower pressure on ecosystems.
