water pollution essay very easy
Answers
Answer:
Water is the most important resource for survival on a planet. It is the essence of life on our planet – Earth. Yet if you ever see a river or lake around your city, it would be evident to you that we are facing a very serious problem of Water pollution. Let us educate ourselves about water and water pollution. Two-thirds of the Earth’s surface is covered by water, seventy-six perfect of your body is made up of water.
As you already know water is everywhere and all around. However, we have a fixed amount of water on earth. It just changes its states and goes through a cyclic order, known as the Water Cycle. The water cycle is a natural process that is continuous in nature. It is the pattern in which the water from oceans, seas, lakes, etc gets evaporated and turns to vapor. After which it goes through the process of condensation, and finally precipitation when it falls back to earth as rain or snow.
Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers, and groundwater) usually caused due to human activities. Water pollution is any change, minor or major in the physical, chemical or biological properties of water that eventually leads to a detrimental consequence of any living organism. Drinking water, called Potable Water, is considered safe enough for human and animal consumption.
Sources of Water Pollution
- Domestic Waste
- Industrial effluents
- Insecticides and pesticides
- Detergents and Fertilizers
Some of the water pollutions are caused by direct Sources, such as factories, waste management facilities, refineries, etc, that directly releases waste and dangerous by-products into the nearest water source without treating them. Indirect sources include pollutants that infuse in the water bodies via groundwater or soil or via the atmosphere through acidic rain.
Effects of Pollution of Water
The effects of Water Pollution are:
Diseases: In humans, drinking or consuming polluted water in any way has many disastrous effects on our health. It causes typhoid, cholera, hepatitis and various other diseases.
Eradication of Ecosystem: Ecosystem is extremely dynamic and responds to even small changes in the environment. Increasing water pollution can cause an entire ecosystem to collapse if left unchecked.
Eutrophication: Chemicals accumulation and infusion in a water body, encourages the growth of algae. The algae form a layer on top of the pond or lake. Bacteria feed on this algae and this event decreases the amount of oxygen in the water body, severely affecting the aquatic life there
Effects of the food chain: Turmoil in food chain happens when the aquatic animals (fish, prawns, seahorse, etc) consume the toxins and pollutants in the water, and then the humans consume them.
Prevention of Water Pollution
The best way to prevent large-scale water pollution is to try and reduce its harmful effects. There are numerous small changes we can make to protect ourselves from a future where water is scarce.
Conserve Water: Conserving water should be our first aim. Water wastage is a major problem globally and we are only now waking up to the issue. Simple small changes made domestically will make a huge difference.
Treatment of sewage: Treating waste products before disposing of it in water bodies helps reduce water pollution on a large scale. Agriculture or other industries can reuse this wastewater by reducing its toxic contents.
Use of environment-friendly products: By using soluble products that do not go on to become pollutants, we can reduce the amount of water pollution caused by a household.
Conclusion
Life is ultimately about choices and so is water pollution. We cannot live with sewage-strewn beaches, contaminated rivers, and fish that are poisonous to drink and eat. To avoid these scenarios, we can work together to keep the environment clean so the water bodies, plants, animals, and people who depend on it remain healthy. We can take individual or teamed action to help reduce water pollution. As an example, by using environmentally friendly detergents, not pouring oil down the drains, reducing the usage of pesticides, and so on. We can take community action too to keep our rivers and seas cleaner. And we can take action as countries and continents to pass laws against water pollution. Working together, we can make water pollution less of a problem—and the world a better place.
Answer:
Water pollution occurs when unwanted materials enter in to water, changes the quality of water [1] and harmful to environment and human health [2]. Water is an important natural resource used for drinking and other developmental purposes in our lives [3]. Safe drinking water is necessary for human health all over the world. Being a universal solvent, water is a major source of infection. According to world health organization (WHO) 80% diseases are water borne. Drinking water in various countries does not meet WHO standards [4]. 3.1% deaths occur due to the unhygienic and poor quality of water [5].
Discharge of domestic and industrial effluent wastes, leakage from water tanks, marine dumping, radioactive waste and atmospheric deposition are major causes of water pollution. Heavy metals that disposed off and industrial waste can accumulate in lakes and river, proving harmful to humans and animals. Toxins in industrial waste are the major cause of immune suppression, reproductive failure and acute poisoning. Infectious diseases, like cholera, typhoid fever [6] and other diseases gastroenteritis, diarrhea, vomiting, skin and kidney problem are spreading through polluted water [7]. Human health is affected by the direct damage of plants and animal nutrition. Water pollutants are killing sea weeds, mollusks, marine birds, fishes, crustaceans and other sea organisms that serve as food for human. Insecticides like DDT concentration is increasing along the food chain. These insecticides are harmful for humans
