Environmental issues in Kenya include deforestation, soil erosion, desertification, water shortage and degraded water quality, flooding, poaching, and domestic and industrial pollution. Water resources Water resources in Kenya are under pressure from agricultural chemicals and urban and industrial wastes, as well as from use for hydroelectric power. The anticipated water shortage is a potential problem for the future. For example, the damming of the Omo river by the Gilgel Gibe III Dam together with the plan to use 30% to 50% of the water for sugar plantations will create significant environmental problems. Up to 50% of Lake Turkana's water capacity will be lost. Had there been no planning of the irrigation of sugar plantations, the dam itself might have had a net positive effect to the environment, due to the emission-less power generation of the dam. Water-quality in Kenya has problems in lakes, (including water hyacinth infestation in Lake Victoria), have contributed to a substantial decline in fishing output and endangered fish species. Animal poaching There are a wide variety of wildlife species in Kenya, whose habitats are threatened by encroachment of human development and destruction. In rural Kenya, poachers are one of the main threats to endangered animals. Michael Werikhe aka Rhino Man, made huge contributions to early Kenyan wildlife conservation. Werikhe walked thousands of kilometres and raised millions of dollars to fund White Rhino conservation projects. The Blue Wildebeest is currently abundant, but like other more endangered species feels the pressure of habitat reduction. Wildlife facing threats to poaching and trophy hunting include lions, elephants, gazelles, and rhinos. In February 2020, poachers in Kenya killed two white giraffes. The female white giraffe and her calf were found dead in Garissa County, in the North-East part of the country. There now remains only one male, white giraffe left in the world. Other critically endangered species in Kenya include the Tana River Mangabey, Black Rhino, Hirola, Sable Antelope, and Roan Antelope. Laws, regulation, and deterrence During Kenya's colonial era (1895-1963), elephant and rhino hunting was viewed as an elite sport by British colonizers. Post-independent Kenya saw a decrease in over half of the elephant population during the period of 1970 to 1977, even though the country banned elephant hunting in 1973. In 1977, all animal hunting was banned in Kenya. The Kenya Wildlife Service was then established in 1989. The state corporation responded to high levels of poaching, insecurity in
