Not a lake of death. That's what it does to corpses, not living animals.Quoting the article:
Quoting the article:
"No one knows for certain exactly how they die, but it appears that the extreme reflective nature of the lake's surface confuses them, and like birds crashing into plate glass windows, they crash into the lake."
"Animals that become immersed in the water die and are calcified."
So the lake seems to kill the birds.
The lake is the only regular breeding area in East Africa for the 2.5 million Lesser Flamingoes, whose status of "near threatened" is a consequence of their dependence on the single breeding location. As salinity increases, so do the number of cyanobacteria, and the lake can support more nests. These flamingoes, the single large flock in East Africa, gather along saline lakes in the region, where they feed on Spirulina (a blue-green algae with red pigments). Lake Natron is a safe breeding location because its caustic environment is a barrier against predators trying to reach their nests on seasonally-forming evaporite islands. Greater Flamingo also breed on the mud flats.
The area around the salt lake is not inhabited but there is some herding and some seasonal cultivation. Threats to the salinity balance from increased siltation influxes will come from more projected logging in Natron watersheds and a planned hydroelectric power plant on the Ewaso Ng'iro across the border in Kenya. Although development plans include construction of a dike at the north end of the lake to contain the fresh water, the threat of dilution to this breeding ground may still be serious. There is no formal protection.
A new threat to Lake Natron is the proposed development of a soda ash plant on its shores. The plant would pump water from the lake and extract the sodium carbonate to convert to washing powder for export. Accompanying the plant would be housing for over 1000 workers, and a coal-fired power station to provide energy for the plant complex. In addition, there is a possibility the developers may introduce a hybrid brine shrimp to increase the efficiency of extraction.

According to Chris Magin, the RSPB's international officer for Africa, "The chance of the lesser flamingoes continuing to breed in the face of such mayhem are next to zero. This development will leave lesser flamingoes in East Africa facing extinction". Currently a group of more than fifty East African conservation and environmental institutions are running a world-wide campaign to stop the planned construction of the soda ash factory by Tata Chemicals Ltd of Mumbai, India and National Development Corporation of Tanzania.
