Conservation of water resources
Access to clean and adequate water sources is a major problem facing the world today.
Steps have to be taken to conserve this dwindling resource. Even though water is
renewable resource, its overuse and pollution make it unfit for use. Discharge of
untreated or partially treated sewage, agricultural chemicals and industrial effluents in
water bodies are major contaminants. They pollute water with nitrates, metals and
pesticides. Most of these chemicals are non-biodegradable and reach human bodies
through water. Water pollution can be controlled by treating these effluents suitably
before releasing them in water bodies.
