The Basics on Pollution


by Monique

What is pollution? Pollution is the chemicals in the air that harm humans and damage the environment. These chemicals come from human activity and can be primary or secondary. The pollution is killing many people each year.Pollution does not only affect humans and the environment but also plants and animals. It's a problem affecting the entire ecosystem.

Pollution is the chemicals in the air that harm humans and the environment though it is harmful to plants and animals to.The plants are affected by acid rain. Acid rain is pollution mixed with rain to create acid rain.The acid rain then falls all over the soil affecting the plants growth and animals feeding grounds.

These chemicals come from human activities. Pollutants may be primary or secondary. Primary pollutants come from a process, such as carbon monoxide gas from cars,or sulfur dioxide from factories. Primary pollutants are directly emitted from a process. On the other hand, secondary pollutants come from two primary pollutants mixed together.These harmful pollutants are damaging our earth!

Pollution is killing many people each year. The World Health Organization says 2.4 million people die each year because of air pollution.More deaths are linked to air pollution than car accidents. Health affects of pollution can be long term or short term affects.Short term affects include irritation of the eyes, nose and throat,you can even get pneumonia. Long term affects include chronic respiratory disease,lung cancer,heart disease and damage to the brain, liver, nerves ans kidneys. If we don't try to stop air pollution more and more people will die each year.

The pollution in the air is not going to stop on its own,we have to do something as a world to stop pollution. People will keep dying,the earth will become more damaged.The chemicals from factories and cars will not stop. These harmful chemicals will keep damaging humans and our environment if we don't do something about this.
