Development activities on the hydrosphere cause water pollution. The hydrosphere includes all the water present on a planet. Development activities such as constructing dams, sewage disposal, industrial development, fishing, mining, etc. cause water pollution.
However, we can cut down the pollution levels by bringing strict regulations such as the treatment of waste from households and factories before disposing them to water bodies. According to the reports, about 20 percent of fresh water is withdrawn worldwide due to factories. Dams are useful to generate electricity, but they disturb the water ecosystem.
Water pollution caused due to the development activities on the hydrosphere leads to food chain disruptions, groundwater contamination, destruction of the ecosystem, spread of diseases, eutrophication, and affects aquatic as well as human life.
