Why is polluting really bad?


This week a TPL Kids visitor has wondered: Why is polluting really bad?


Pollution can take many forms, this includes (but is not limited to): air, water, noise, and soil. It is the act of making land, water, air or other parts of the environment dirty or unsafe. Pollution impacts humans, animals, and the earth.


According to the UN (United Nations) World Health Organization, 9 out of 10 people breathe polluted air, which kills 7 million people per year. Polluted air is the result of mobile, stationary, area, and natural sources. This includes everything from cars to power plants to wood burning fireplaces to volcanoes.


According to UNESCO (United Nations Educational, Scientific and Cultural Organization), more than 90% of sewage and 70% of industrial wastes in the developing world are dumped untreated into surface waters where they pollute water supplies and coastal waters. According to WHO (World Health Organization) 2 in 10 people in the world who do not have access to safe and affordable drinking water and 5 in 10 do not have access to adequate sanitation.


So the next time you see a no swim advisory sign, consider how polluted the water must be for such an advisory to be put out.
