Effects of Water Pollution

Updated: Apr 16, 2021

70% surface of the planet Earth is covered by water but the oceans hold about 97% of all Earth's water so that actually all creatures in the world can only use 3% of Earth’s water for drinking and living.


With the rapid development of urban areas and industrial factories, more and more waste discharged into the environment causes water pollution, making billions of people in the world unable to access clean and safe water. It goes without saying that the effects of water pollution on human life as well as natural life is extremely severe.


Currently, about 1.1 billion people in the world do not have access to clean water. About 2.7 billion people cannot drink fresh water at least once a year. In addition to the scarcity of clean water sources, inadequate sanitation also affects people's health. It gives rise to a variety of water pollution-related diseases such as diarrhea, cholera, typhoid, etc. Researches show that about 2 million people, most of them are children, have died every year from diarrhea or cholera because of the lack of clean water.


What is Water Pollution?

The World Health Organization (WHO) defines contaminated water as water whose composition has been changed to the extent that it cannot be used anymore. It is toxic water and the cause of various diseases such as diarrhea, cholera, dysentery, typhoid and polio, killing more than 500,000 people each year all around the world.



The main water pollutants are associated with bacteria, viruses, parasites, fertilizers, pesticides, pharmaceuticals, nitrates, phosphates, plastics, fecal waste, and even radioactive substances. These substances do not always change the water's color but cannot be used in daily life.
