So far, oil drilling in the largest freshwater lakes in the United States — the Great Lakes — has been stalled by opponents. That isn’t true on the African continent, however, where itt may be only a border dispute between Malawi and Tanzania that slows oil exploration in Lake Malawi.
Tilapia and other fish make the lake an important source of food for Malawi, one of the world’s most underdeveloped countries. The lake is believed to host more species of fish than any other body of freshwater on Earth.
While the government of Mozambique declared the lake a reserve to preserve diverse species, that country only lays claim to about a quarter of the lake.
