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....
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 obvious that nothing happens. We...
There are several sources of water pollution ranging from sewage and fertilizers to soil erosion. The impact of water pollution on wildlife and their natural habitat can be immense. While it may seem like preventing water pollution can be an overwhelming subject to tackle, there are also a number of things that the average person can do to help stop water pollution. Tips on Preventing Water Pollution The best solution for water pollution is prevention. While pollution that has already occurred is a current threat to all life on Earth, attempts to clean it up may cause even more harm.There are several steps that can be taken to help prevent water pollution from getting worse. Keep Machinery in Good Working Order The oil used to lubricate engines in all types of machines needs to be changed regularly. When the oil is changed, it presents a number o...

⦿ Surface Water Pollution - Most common type, you can visually see the pollution floating (plastic containers or oil and gasoline spills). ⦿ Ground Water Pollution – This becomes more relevant as it affects our drinking water. It become infected by toxic chemicals. ⦿ Microbial Pollution – Found in the countries who don’t have the facilities to cure the water so the bacteria and viruses grow in the water. The people have no other way of getting water so they are forced to drink it. WHAT CAUSES WATER POLLUTION? ⦿ Wastewater ⦿ Marine dumping ⦿ Industrian waste ⦿ Radioactive waste ⦿ Oli pollution ⦿ Underground storage ⦿ Global warming WHY IS IT A PROBLEM? ⦿ It causes worldwide disasters and deaths. ⦿ It may not damage our health immediately but can be harmful after long time. ⦿ Industr...
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 around that area. We can prevent this from...
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. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its...
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 advantages of hyd...
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. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportati...
These are air pollution, water pollution , endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of mile...
Water pollution caused by chemicals and sewer water dumped into water. Soil pollution caused by chemicals released into underground lakes. Natural resources running out Rainforests are being cut down constantly. There are not enough fresh water in some parts of the world. Fossil fuels are used too much and most of its reserves will be used up by 2050. Endangered species 40 percent of all organisms are endangered All the different species are important for biodiversity Habitat loss and hunting are the most widespread cause of species endangerment . Climate change Climate change is a change in the statistical distribution of weather over periods of time. The Earth's average surface temperature has risen by 0.76° C since 1850. Most of the warming that ha...

Introduction The name Australia is derived from the Latin Australis, meaning of the south. In land area, Australia is the sixth largest nation, its territory is 7,686,850 sq km and its population reaches today over 20,5 million people. It is the only nation to govern an entire continent and its outlying islands. Australia's capital is Canberra, the only city with its own territory. It was built in the early 1900s just to be the capital. The official language is English and the official name of Australia is the Commonwealth of Australia. Australia is located on the Southern Hemisphere (because of that Australia is also called "A land down under"). 2 . Geographical position Australia is an island continent and...
However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever. The scale of human pressures on ecosystems everywhere has increased enormously in the last few decades. Since 1980 the global economy has tripled in size and the world population has increased by 30 percent. Consumption of everything on the planet has risen- at a cost to our ecosystems. In 2001, The World Resources Institute estimated that the demand for rice, wheat, and corn is expected to grow by 40% by 2020, increasing irrigation water demands by 50% or more. They further reported that the demand for wood could double by the year 2050; unfortunately, it is still the tropical forests of the world that supply the bulk of the world's demand for wood. In 1950, about 15 percent of the Earth's land surface was covered by rainforest. Today, more than half has already gone up in smoke. In fewer than fifty years, more than half of the world's tropical rainforests have fallen victim to fire and the chain saw, and the rate of destruction is still accelerating. Unbelievably, more than 200,000 acres of rainforest are burned every day. 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...

Impact of oil on coastal activities The effects of a particular oil spill depend upon many factors, not least the properties of the oil. Contamination of coastal amenity areas is a common feature of many spills leading to public disquiet and interference with recreational activities such as bathing, boating, angling and diving. Hotel and restaurant owners, and others who gain their livelihood from the tourist trade can also be affected. The disturbance to coastal areas and to recreational pursuits from a single spill is comparatively short-lived and any effect on tourism is largely a question of restoring public confidence once clean-up is completed. Industries that rely on a clean supply of seawater for their normal operations can be adversely affected by oil spills. If substantial quantities of floating or sub-surface oil are drawn through intakes, contamination of the condenser tubes may result, requiring a reduction in output or total shutdown whilst cleaning is carried out. Biological effects of oil Simply, the effects of oil on marine life, are caused by either the physical nature of the oil (physical contamination and smothering) or by its chemical components (toxic effects and accumulation leading to tainting). Marine life may also be affected by clean-up operations or indirectly through physical damage to the habitats in which plants and animals live. The main threat posed to living resources by the persistent residues of spilled oils and water -in- oil emulsions ("mousse") is one of physical smothering. The animals and plants most at risk are those that could come into contact with a contaminated sea surface...
