Causes Of Water Pollution Essay

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

On average 700 people worldwide drink contaminated water worldwide. The leading cause to water pollution is sewage and waste. On average the world dumps 5-10 million tons of untreated industrial waste into streams, rivers and oceans. In 2011 a tsunami that hit Japan sent a forty-three and half miles long island made of debris floating out into the pacific ocean. Also from causes of the tasumi it promoted the Japanese government to dump two million of radioactive water into the pacific ocean as well. In 1989 Exxon accidently spilled eleven million metric tons of crude oil into the sea off of Alaska’s Prince Williams Sound. The disaster cover 3,000 square miles.

it has in store for the future if things do not improve. It will also explore

In our society we are encountering environmental issue with water pollution. The world development of modern agriculture and industry, water pollution has been a major problem.

There has been an increased presence within the water of toxic chemicals, metals, and disease causing microorganisms throughout the years. In general, the main cause of water pollution is the sewage pipes as well as the factories which are slowly becoming more in control. Although the contamination of water has slowly began to be stopped there is still heavy contamination from the waterways from the farmlands which tend to carry fertilizers, pesticides, as well as organic matter. Rain is a major contributor to water contamination from the different acids and heavy metals which fall with the rain contribute to the water

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

 Water pollution is a problem that most everyone would agree does exist.  The toxic substances in the water can kill the plant life, animal life, and in some cases, the human life.  In Teluk Mengkuang, Sijangkang,  156 ponds filled with tiger prawns died

Air and water pollution is one of the biggest problems the environment faces today. It is one of the highest leading cause of death. Air and water pollution has been affecting the environment for many years causing many diseases among people especially children. I will study and examine the early childhood growth between two countries which are Australia and Tanzania. I will discuss how clean and polluted their air and water is for each country. Their access to clean water. I will also explain the effects that can occur when water is contaminated. How children are affected when they don 't have access to primary essentials and how each country and their environment and living condition might threatened a child 's life.

A reason that water pollution is a problem today is because many people don’t realize that they are hurting out water supplies when they really are. There are many pollutants that hurt our water supply such as farming. When farmers spray their fields with chemicals and apply fertilizers. Some of these chemicals reach the river, and animal urine and manure may be washed into the river. Another cause of water pollution is from accidents, such as tanker spills. Accidents with chemicals may cause river pollution as well. Mining can be another cause because the dusts and minerals get washed into the rivers. Seepage is another cause of water pollution. Because chemicals from waste dumps join the groundwater flow into the river. Urban Wastes is a major cause because the sewage comes from toilets, sinks, and industrial processes. This causes many human diseases such as diarrhea, dysentery, hepatitis, and cholera.

Most pollution comes from land.“Did you realize that polluted water might even be a problem in your own home, even if you live in a city with treated water supplies?”First of all,sadly water pollution is in our homes when the government “treats” out water they are actually putting harmful chemicals in the water to “clean” it."The problem is that normal degradation leaves particles that can still be harmful to living things — nanoparticles and microparticles,In addition, plastic is not biodegradable well it takes 10,000 years for one water bottle to biodegrade so it last very long and for that times it will continue to harm many animals.“Water pollution is a major contributor to declining health and wellbeing of animals, plants, ecosystems, and even human beings in the United States and in the rest of the world.”As you can see,most pollution comes from land for example plastic comes from factories then ends up in the ocean.

70 % of our Earth surface is covered by water and almost 60% of the human body contain water for nutrient transportation. The unique characteristic of water is water molecule is the only substance in this Earth that exist in all three physical states of matter which are solid, liquid and gas. All human beings need water to survive. The national development over the years cause the rate of water pollution increased. According to Gebre & Rooijen (2009) water pollution can be considered as a sign that derives from economic growth and is a common phenomenon in urbanized cities in developing countries. In general, there are three main issues that related to water pollution which are the causes, effects and the way to decrease this problem.

Chemical waste from factories dump their un wanted waste into rivers, lakes or ponds as well. One major component that effects the water

Water pollution has become an increasing problem on the earth, which is affecting human and animal lives in all ways possible. Water pollution is the contamination of drinking water by the poisonous pollutants generated by the human activities. The Earth's water is getting polluted through many sources such as urban runoff, agricultural, industrial, sedimentary, animal wastes, and other human activities. All the pollutants are very harmful to the environment. Human population is increasing day by day, hence their needs and competition leading pollution to the top level. 62 of New Zealand's waterways are unsafe to swim in due to pollution and 44% of New Zealand’s lakes are defined as polluted for recreation. Mankind cannot survive without
