Air and Water pollution

One cause on air pollution at this time is pollution in the ozone layer. The ozone layer over the arctic has thinned this winter because of air pollution. The holes on the ozone layer make the ultraviolet light come in and reach Earth's surface. At this time children, adults, and old people are suffering and will continue suffering from skin cancer; which is a disease that is increasing already in the world. I also found information about this in Wikipedia. I saw something called ozone depletion. The ozone depletion describes how the stratosphere of Earth is changing each day by pollution. The process by which the ozone layer is changing is called catalytic destruction of ozone by atomic chlorine and bromine. CFC's are very dangerous they are one of the most dangerous compounds that destroy the ozone layer. CFS's can come from refrigerators, Air conditioners, insulation, foam, industrial cleaning agents etc. As you can see air pollution is not harming just Earth it is also harming a lot of people's health.

In a web page called Air pollution causes and effects I found that in American office buildings that the air inside the buildings is more polluted than the air outside. A very dangerous illness that is caused by air pollution is lung cancer. Lung cancer is caused by Radon which is a gas that is made by decay of uranium. Radon gets in the air of buildings, through pores and little holes in concrete when indoor pressure is less than the pressure of gasses in the soil. Indoor air will be healthier than outdoor air if people use an energy recovery ventilator to make a consistent supply of fresh air and then air leaks in the shell of the homes. Other causes of air pollution are that because people are burning rain forests more carbon dioxide is released into the atmosphere. As you know trees are major sources to make oxygen. If people continues to burn forests here is going to be less oxygen and more carbon dioxide.

I got information from a web page called water pollution and society. Here says that pathogens are a cause of water pollution. They can cause skin disease and respiratory diseases. Pollution in rivers and streams in the United Kingdom has increased during the 20th century. Three forms of water pollution are petroleum, radioactive substances, and heat. A major source of water pollution is municipal water pollution. It consists of wastes of water from homes and public establishments. Agriculture is also a source of water pollution because by farming a lot of organic and inorganic pollutants get to the ground water. In a web page called water pollution guide I found that water pollution can damage the health of humans and animals. It may not immediately damage it but during time it could. I also found the ways by which water pollution is made. One way is when people throws garbage or wastes to the water. This makes the water very dirty and contaminated. Another way is global warming. When the water increases its temperature marine organisms can die. Also oil pollution which is made by boats that navigate they left behind the oil contaminating the water.

Well what I really think about air pollution is that it is an important illness for humans and for Earth. Millions of people are dying because of the harm air pollution makes to them. We need to think for a way to solve this problem because we cannot make it increase it any more. About water pollution; it’s just the same thing as air pollution the same problems it’s just so terrible. I think water is the most important source for humans to live. Can you imagine what happens if all the water in the world would be contaminated. It’s obviously that living things would not survive.

In my next post I will like to talk about water pollution in the Pacific and Atlantic ocean. With this information would like to compare their water pollution.
