Effects of water pollution.

The effects of water pollution can be catastrophic, depending on the kind of chemicals, concentrations of the pollutants, and where they are polluted. Below, we shall see a summary of the effects of water pollution.

Make sure you read the factsheet page for some unfortunate incidents of water pollution in recent times.

The effects of water pollution are varied and depend on what chemicals are dumped and in which locations.

Many water bodies near urban areas (cities and towns) are highly polluted. It is usually the result of both garbage dumped by individuals and dangerous chemicals legally or illegally dumped by manufacturing industries, health centers, schools, and marketplaces.

Death of aquatic (water) animals

The main problem caused by water pollution is that it kills organisms that depend on these water bodies. Dead fish, crabs, birds and seagulls, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat (living environment).

Disruption of food-chains

Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals. Later, these animals are consumed by fish and shellfish, and the food chain continues to be disrupted at all higher levels.

Eventually, humans are affected by this process too. People can get diseases such as hepatitis by eating seafood that has been contaminated. In many poor regions, there is frequently an outbreak of cholera and diseases as a result of poor drinking water treatment from contaminated waters.

Destruction of ecosystems

Ecosystems (the interaction of living things in a place, depending on each other for life) can be severely changed or destroyed by water pollution. Many areas are now being affected by careless human pollution, and this pollution is coming back to hurt humans in many ways.
