The rivers and seas have been us as dumping grounds for all kinds of waste materials. We throw rubbish into the drains that lead to the rivers.Water pollution affects plants and organisms living in these bodies of water ; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.
Factories dispose of their waste materials into the rivers.
Garbage strewn across a sandy areaThese waste materials contain toxic and poisonous substances.The rivers and sea can become polluted.The poisonous waste material can kill fish. Since we also depend on our rivers and sea for food,our health can be affected if we eat fish from polluted waters. Sometimes oil from ships spills into the seas and oceans. The oil not only pollutes the seas and the oceans but pollutes the beaches too. This can destroy the habitat of water organisms.
