Causes and consequences of water pollution

Learn how the pollution of rivers, seas and lakes endanger the survival of the planet and all its inhabitants

Water is a  basic resource that  guarantees the life of all living beings on the planet. However, its scarcity and pollution cause millions of people to have poor access to this much-needed asset. Although there are processes such as water treatment or desalination that facilitate its treatment, use and consumption in areas with quality or supply problems, it is first necessary to avoid its contamination.

In this video we show you what are the main causes of water pollution, as well as its effects.

The human being is the main responsible for water pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore contaminate groundwater.

In the same way, the pesticides used in agricultural fields filter through underground channels and reach the consumption networks; And also as a result of accidental spillage of oil.

What are the effects of water pollution?

And what are the main consequences of this? Firstly, the disappearance of biodiversity and aquatic ecosystems. Also, humans are harmed by the alteration in the food chain and by contracting illnesses when drinking or using contaminated water.

For all this, we must ensure water availability, its sustainable management and sanitation for all, as reflected in the sixth of the Sustainable Development Goals adopted by the United Nations in the 2030 Agenda.
