Water pollution: causes and effects

Water pollution: causes and effects One of the most important resources on our earth is water. Clean water is vital to our communities, economy, and most of all, our health. • In fact, humans are made up of more than 60% water, and we need clean water to survive. Unfortunately, much of our water on earth is polluted and it is one of the major crises facing the world today. There are many causes of water pollution and we need to do something to save this precious resource. • Humans depend on clean water to not only survive but also to thrive. Sadly, to get clean water is becoming harder and harder each year. So, what is causing water pollution? 1) Fast urban Development (Urbanisation) The building of new roads, houses, and industries affect the cleanliness of the water through the use of detergents, chemicals, and exhaust emissions. When it rains, these chemicals are washed into the rivers and streams, and eventually into the drinking water supply. 2) Wrong Sewage Disposal More and more, improper sewage disposal is becoming a major world issue. Every time you flush, the waste goes somewhere…either to a sewage treatment facility and from there, remaining sewage is dumped into the oceans. 3) Fertilizer Run-Off With fertilizers people try to keep their yards vibrant green and weed-free, fertilizers play a large roll in the cause of water pollution on this planet. The result is dangerous algae blooms which eventually lead to the extinction of many underwater plants, as well as fish. 4) Oil Spills • Water pollution caused by oil spills from tankers and ship travel. Oil spills don’t dissolve in water and forms a thick sludge. Also while these types of oil spills do cause water to become polluted, oil leaks from vehicles and mechanic trades are another main cause of water pollution. The spilled oil mixes with groundwater and makes its way into streams and rivers. 5) Chemical Waste Dumping Big factories are dumping chemicals into the ocean. Highly toxic substances such as detergents, polychlorinated biphenyls, and lead are discharged into our environment every day. 6)Radioactive Waste Discharge There are nuclear power plants all around country, and the government allows “permissible levels” of radioactive water to be released into the environment every day. And, while it’s permissible–it doesn’t mean it’s safe. Likewise, accidents have been known releasing horribly high amounts of harmful radioactive chemicals to be released into the air, water, and soil. How to reduce the risks of water pollution
