In 2007, Tata Group joined forces with a Tanzanian company to build a soda ash extraction plant in Tanzania. Environmental activists oppose the plant because it would be near Lake Natron, and it has a very high chance of affecting the lake's ecosystem and its neighbouring dwellers, jeopardising endangered lesser flamingo birds. Lake Natron is where two-thirds of lesser flamingos reproduce. Producing soda ash involves drawing out salt water from the lake, and then disposing the water back to the lake. This process could interrupt the chemical makeup of the lake. 22 African nations signed a petition to stop its construction.
