The Mithi River is a river on the island of the city of Mumbai, India. It is a confluence of tail-water discharges of the Powai and Vihar lakes. The river is seasonal and rises during the monsoons. The overflowing lakes also contribute to the river flow, which is stopped by a dam at other times. The river has been polluted by dumping of raw sewage, industrial waste and municipal waste into the river. Besides this, illegal activities like washing vessels, animals, and oily drums, discharge of unauthorised hazardous waste are also carried out along the course of this river. The water with a mixture of sewage and industrial waste is a threat to marine life. The river bed is full of sludge, garbage, and vegetation growth like water hyacinth in many parts. Many youngsters of the city have taken the initiative to stop polluting and destroying the Mithi river. They have held many campaigns and awareness protests to make the river in a better condition. Sign this petition to help these youngsters make a change for the environment.
