What Causes Water Pollution?

What Causes Water Pollution?

Water pollution is a major cause of illness and death. It affects all lifeforms and ecosystems, and it can harm aquatic animals, plants, and humans. There are many different causes of water pollution.

A few of the most common types include agriculture, industrial waste, and natural phenomena. The biggest problem is agricultural runoff. Waste water from farms is often dumped into rivers, lakes, and oceans. In addition, fertilizers and herbicides can harm aquatic ecosystems.

Sewage is another big source of water pollution. The United Nations estimates that 80% of the world’s waste goes back into the environment without treatment. As a result, toxic chemicals and heavy metals can be ingested by humans and animals.

Industrial facilities can also release hazardous materials into the water. Radioactive waste can harm marine resources. And toxic chemicals and heavy metals can disrupt the food chain and increase the risk of cancer.

Other factors that contribute to water pollution include deforestation, construction of new buildings, and earthquakes. These changes can cause a change in the chemical composition of the water.

In addition, industrial waste can cause groundwater to leak into the rivers. This can lead to a dead zone.

Another type of pollution is eutrophication. This occurs when a lot of nutrients enter the water. This can lead to algae blooms, which can cause the extinction of underwater plants.

In addition, invasive species can have a dramatic impact on aquatic communities. These species feed on other creatures, such as bats, and can change the balance of life in the area.
