The livelihoods of thousands of people who depend on Lake Victoria are at risk as pollution and over-harvesting drive hundreds of species to extinction.
According to a report by the International Union for Conservation of Nature (IUCN), which assessed the global extinction risk of 651 freshwater species native to Lake Victoria, 20 per cent of these species and 76 per cent of the 204 fresh water species which are only found in the lake, are at risk of extinction.
