The correct options are

B Overpopulation

D Water pollution


Chennai had a huge water crisis in 2019 as a huge number of trees had been cut down in the name of urban development and mass scale infrastructure making. Many rivers were polluted by garbage. More people and less rain water harvesting was a major cause of the issue. Rain water harvesting is a technique of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff).
