Earth Pollution

Decent Essays

I'm going to start off my essay by talking about "earth pollution". There are seven different types of earth pollution. Starting of with water pollution and air pollution, I think these would be the most common and prevalent forms of earth pollution. Water and air are both extremely important to the enviroment. The rest is, soil pollution, thermal pollution, radioactive pollution, noise pollution and light pollution. There is also air pollution that works in a green house infect. Which can warm up the earth. The green house affect can be caused by sulfur dioxide and carbon dioxide. Soil pollution is caused by, " Human made chemicals or other alternation in the natural soil environment". It is meanly caused by agricultural chemicals, industrial stuff and people who do not take good care of their trash. An example of this is (littering). Thermal pollution is a process that changes water quality for the worse by the water tempter. The main way that thermal pollution is active, is by big "Power Plants" using water as a coolant. Radioactive pollution is when are there radioactive particles in the air, and this is caused by human actions. It is accidental or on tentonal . Noise pollution is basically where there is a lot of noise that people just do not want. It can even damage stuff like your hearing not being able to sleep as well and it can cause high stress levels, and it has more effects than that. When I first saw noise pollution as one of the seven different types of earth pollution I thought it was kind of weird, but now that I looked in to it, it makes more sence. For the last one of the seven types of earth pollution (which is Light pollution) I decided to take a closer look at it then the others. So, I watched a documentary about light pollution. Light pollution is when a lot of lights, mainly coming from big cities, this is bad because it makes it harder to see the stars. What makes so you can't see the stars is light that shines up on dust particles. In the past people lite things up with torches or lamps but now all over the world people are lighting things up with electrice lights. Astronomers have noticed that when they want to get a good look at the night sky they have to go farther away from big
