Water Pollution

Water pollution is the result of dumping chemicals and other foreign objects into rivers, sea and dams. It affects plants, humans, and animals living in or drinking the water. A lot of diseases are caused from water pollution. People in other countries have to drink and live with this polluted water. People get sick and can even die!! All the sewage flows into the lake or river and the people have to drink it!! They even have to take baths in this nasty water. Worldwide, nearly 2 billion people drink contaminated water that could be harmful to their health.

Causes of water pollution

Humans are the main causes of water pollution. http://filtercon.files.wordpress.com/2013/02/water-pollution.jpg Most of our waste would end up in the sea or nearby rivers. Other things also contribute to water pollution such as

Industrial Waste

Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. http://labsaints.com/wp-content/uploads/water-pollution.jpg

Radioactive Waste

Nuclear waste is produced from industrial, medical and scientific processes that use radioactive material. Nuclear wastes comes from a number of sources such as, ioperations conducted by nuclear power stations produce radioactive waste. Waste is also produced in the nuclear fuel cycle which is used in many industrial, medical and scientific processes. http://forums.tf2maps.net/geek/gars/images/2/3/6/3/lavatest0006.jpg

Atmospheric Deposition

Atmospheric Deposition is the pollution of water caused by air pollution. In the atmosphere, water particles mix with carbon dioxide sulphur dioxide and nitrogen dioxide, this forms a week acid. http://swagata.edublogs.org/files/2012/02/acidraincause-2d2watp.jpg

Oil Pollution caused by oil spills from tankers and oil from ship travel. Oil does not dissolve in water and forms a thick sludge. http://oceanworld.tamu.edu/resources/oceanography-book/Images/ixtox1.jpg

Effects of Water Pollution

Water pollution effects our health and our environment. The water is filled with toxic waste and sewage. Many bodies of water near urban areas are highly polluted. This is the result of both garbage dumped by individuals and dangerous chemicals legally or illegally dumped by industries. The main problem caused by water pollution is that it kills life that inhabits water-based ecosystems. Dead fish, birds, dolphins and many other animals often wind up on beaches, killed by pollutants in their habitat. https://www.youtube.com/watch?v=VlB5je6MKUw http://english.people.com.cn/200604/30/images/0429_C66.jpg Eventually, humans are affected by this process as well. People can get diseases such as hepatitis, cholera and also can get food poisoning by eating seafood that has been poisoned. http://www.medindia.net/patients/patientinfo/images/cholera.jpg Swimming in and drinking contaminated water causes skin rashes and health problems like cancer, reproductive problems, typhoid fever and stomach sickness in humans. http://download.thelancet.com/images/journalimages/1473-3099/PIIS1473309906706776.fx1.lrg.jpg That’s why it’s very important to make sure that our water is clean and safe to drink. Oil spills in the water causes animal to die when they ingest it or encounter it. Oil does not dissolve in water so it causes suffocation in fish and birds. http://upload.wikimedia.org/wikipedia/commons/f/fc/Oiled_Bird_-_Black_Sea_Oil_Spill_111207.jpg

Prevention of water pollution

Dealing with water pollution is something that everyone (including governments and local councils) needs to get involved with. Here are a few things we can do to help.

We mustn’t throw rubbish away anyhow. We must always look for the correct waste bin. If there is none around, we must take it home and put it in our trash can. This includes places like the beach, riverside and water bodies. We should use water wisely. We mustn’t keep the tap running when not in use. Also, we can reduce the amount of water we use in washing and bathing. If we all do this, we can significantly prevent water shortages and reduces the amount of dirty water that needs treatment. We mustn’t throw chemicals, oils, paints and medicines down the sink drain. In many cities, our local environment office can help with the disposal of medicines and chemicals. We should buy more environmentally safe cleaning liquids for the use at home and other public places. They are less dangerous to the environment. If we use chemicals and pesticides for our gardens and farms, we should be mindful not to overuse pesticides and fertilizers. If we live close to a water body, we should try to plant lots of trees and flowers around our home, so that when it rains, chemicals from our home does not easily drain into the water. http://www.enviscecb.org/images/Tree3.GIF We can clean up beaches. Once in a while we should visit the beach and volunterily clean up the garbage on the sand or in the water. Water pollution has been extensively documented as a contributor to health problems in humans and marine animal ecosystems. It has a huge impact on our lives, and if we do our part by not throwing trash or chemicals into our water supplies and drains, we can contribute to the improvement of aquatic life and of our health in general. http://2.imimg.com/data2/MJ/UP/MY-1972126/logotowardsnatureletterheaddarkpic-250x250.jpg https://www.youtube.com/watch?v=lgLIMaZAJj0
