Water pollution

Water pollution Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants and for all of us. First, we have to talk about the causes of water pollution. Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Dumping of litter in the sea can also cause huge problems. Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution. Virtually all types of water pollution are harmful to the health of humans and animals...

Water pollution and society

It's based on an article by David Krantz and Brad Kifferstein. I read it through and now I'm trying to give the conclusion of the article as well as express my own opinion. 70 percent of planet Earth's surface contain water. Water is the beginning of life and vital natural resource. It's vital for every living organism. That's why we have to keep the water bodies clean and stop polluting our fresh water. It's hard to believe, but planet Earth is in great danger. People can't see the whole picture. They are being indifferent to the future. Everyone thinks about themselves and tries to find a better and easier way to get rid of garbage and waste. Money is everything for them. Money talks and nobody cares about giving a dollar to save the nature. Usually a person thinks that what difference can he make. But if everybody think so, it's o...

How to deal with water shortage problems?

We need water to live on this planet otherwise life on Earth wouldn't be possible. Many countries suffer from water shortages. There is no fresh water for people usage. It's actually a major problem in the world but what can we do to decrease this? Firstly, people need to realise that there are many other people in the world who does not have accessibility to water. We can decrease it by not wasting water on pointless things for example long showers and watering flowers outside the house. By doing this we will economize water and it may be possible for other people to use fresh water as well. Secondly, it is really important to keep the water fresh and clean but many factories let their sewage into the groundwater which can cause a pollution and the lack of fresh water a...

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another....

Water creates energy

Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos. Hydro-electricity has acquired great significance as a source of energy in the country in the present times and is being put to different uses. The following are the...

Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution . But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines.

Environment

Cars also, like factories, produce poisoned gas in the air. So instead of cars, we should use public transport or a bike, in the name of our enviroment. And what about the factories? Well, we can't remove them from the planet, but they should be built in places, where is less forest and no cities near. Water pollution Secondly, water pollution is also a main issue. Many peole throw rubbish in rivers and lakes. Ships at the sea cause oil problems, where oil flows in the water and causes a lot of damage, like killing the sea animals and also birds, who are on the seacoast, where the oil reaches. When these problems continue, soon we won't be able to swim in a clean body of water and the drinking water becomes unusable. In some places there are floods after the snow melts or in autumn, when raining cause sea level rising...

The importance of the rainforest

That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year. If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years. Massive deforestation brings with it many ugly consequences-air and water pollution , soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming. But who is really to blame? Consider what we industrialized Americans have done to our own homeland...

Keskkonnaprobleemid

Kohutavad õnnetused jõuavad ajakirjandusee, aga sadu miljoneid liitreid naftat vaikselt satub merre iga aasta, põhiliselt mitte õnntuste tagajärjel. Nafta lekked põhjustavad haigusi ja tapavad Suured õnnetused ja lekked-isegi suhtliselt vähetähtis osa ookeani reostusest võib olla vägagi laastav. Sama suur kogus naftat võib teha mõnel alal rohkem kahjut kui teises kohas. Näiteks korallrahnud on nafta suhtes tunduvalt tundlikumad, kui liivarannad. Õlise ainega kaetud karvad või suled ei suuda isoleerida mereimetajat või sukelduvat lindu külmast veest ja kui loom puhastab end ta ka neelab naftat. Isegi, kui nafta kahjustus ei ole koheselt surmav võib see tekitada pikaajalist kahju. Kaladel võib see põhjustada maksahaigusi ja kasvuprobleeme. Kui nafta peaks sattuma mõningatele taimedele nt mangroovidele, siis võibsee seal...
