In Tanzania, one of the major - make that HUGE - threats to the Serengeti ecosystem is a proposal to put a major east/west superhighway right through the middle of the Serengeti. The primary proponent of the highway is the Chinese who are buying up mining and agricultural rights and want rapid transit to the shipping ports on the coast.
This will have devastating effects on all of the species, especially the migratory animals such as Wildebeest and those that follow them such as lions.
