The oil industry is not the only culprit of slow destruction of the ecosystem in the Gulf of Mexico. According to environmental organizations in its latest statement, the area of the Gulf of Mexico the size of Massachusetts to declare a "dead zone". The reason is the severe pollution of the Mississippi River. As environmentalists say, the level of oxygen in the water in the area just sufficient to maintain the normal life of marine animals and plants.
Therefore, recently a number of environmental organizations, including the Council for the Protection of Natural Resources, has been sued by the U.S. Environmental Protection Agency (EPA) for its failure to tighten the regulation of wastewater and the conformity of the river water quality standards. In particular, the defenders called on EPA to test the water in the Gulf of Mexico to the level of nitrogen and phosphorus that stimulate excessive growth of algae that consume precious oxygen in the water. According to the Gulf Restoration Network Organization (GRN), in the Mississippi River reaches 41 percent of sewage from all American businesses, and with them - a huge amount of fertilizers and other chemicals from farms and cities across the country. Every summer, as soon as the water warms up in the Gulf, the volume of these microscopic organisms increases, thereby suppressing the development of the marine ecosystem.
At the same time, environmentalists say, and about poor water quality upstream. Thus, in the season, and Raccoon rivers in Des Moines found extremely high levels of nitrates. In order to keep the water of these rivers was suitable for drinking, requires special handling.
Matthew Roth, Director of Water Policy in the GRN, said that the Mississippi and the Gulf of Mexico for decades been the "national collectors," but now they need to be cleaned.The time has come when the EPA should take appropriate action.
It is worth noting that in 2008, environmentalists have appealed to the Office for Environmental Protection, calling for greater involvement in the control of pollution of the Mississippi River. However, if their application was dismissed with the statement that international water quality standards "are not an effective solution of significant water issues facing the American nation."

Wind farms can cause a localized greenhouse effect .
The results of the study, which was recently conducted by a group of scientists from the University of Albany, New York, raised fears that wind farms can lead to a significant increase in the temperature of the earth. According to researchers, it may even become a serious obstacle to further development of wind energy. Researchers examined data from meteorological satellites, Nolan and Taylor received on the territory of West Texas, which are four largest U.S. wind power. They found that over the past 10 years the temperature of the earth at night has increased by 0.72 degrees Celsius, compared with areas where there are no wind turbines. (For the record, the growth rate of global warming associated with excessive fuel combustion accounts for only around 0.2 degrees Celsius over the same period).
However, the researchers say, and that before coming to any conclusions, further research is needed. In particular, the same data from weather satellites to be collected in other parts of the United States and around the world, where the installed wind power, and carefully analyzed. In addition, scientists warn that the data on such localized "greenhouse effect" should not be compared with data on global warming.
Raising the temperature of the earth in a particular area may be due to two reasons. One is the heat dissipated by the wind turbines and associated electrical transformers and switches. Another factor may be a localized warming of the warm air, which is due to operation of wind turbines is moved from the upper to the lower layers of the atmosphere.
What kind of threat is a "greenhouse effect" in a particular area? First, it is worth noting that the land on which wind turbines are installed and actively used by farmers to grow crops. Therefore, if the findings are confirmed, and the growth temperature of the earth affect the decline in yields, farmers will no longer use the land for agricultural purposes.This in turn could lead to a decrease in the production of cereals and other crops and as a consequence, the emergence of an unfavorable situation with the provision of food.

Storm clouds contribute to global warming: study.
As explained in a recent report from the representative of the Department of Energy Jiva fan, warm air helps to seal storm clouds, causing them to "peak" to climb into the upper atmosphere and capture more heat, especially at night. According to him, global climate models do not account for this effect, since in them the process of formation of storm clouds presented enough detail.
The storm clouds, which are also known as deep convective clouds, are an important part of the climatic cycle. Due to their size, they represent a large portion of solar radiation back into space. However, a recent study showed that with the warm air and the storm clouds are sucking dirt particles in it. These particles inhibit the formation of large raindrops in the cloud, and as a consequence, the "return" of water on the ground as rain.This in turn leads to a further increase in the storm clouds that absorb more water vapor, which is, as scientists believe, a major factor in regional weather systems.
The researchers looked at two different types of storm systems - the warm summer thunderstorms in the southeast of China and the cool windy frontal systems on the Great Plains of Oklahoma. Simulated on a computer, "the storm", scientists have studied in detail how to develop cloud conditions change, such as wind speed and air pollution.They found that air pollution leads to increased summer thunderstorms until a severe storm, which is evidence of a warming effect. The researchers also noted that air pollution causes increased absorption of heat by storm clouds.
According to Fan, the research findings are very important for modeling global warming, but they are calculated only on a particular day - when there are thunderstorms.

The negative impact of modern ecology to wildlife.
It is not for whom no secret that the world is now a terrible environment. Poor environment is harmful to all - people, animals, and in general throughout the animal world. With the harmful emissions are no longer cope or the Amazon forest, or taiga, Siberia.To date, the environment and wildlife adversely affected by the three countries - the U.S., China and India. These countries have not signed contracts, which refers to the preservation of nature. In Russia today, too, a lot of cities where the company pollutes the air. But here at least there is a project of greening of nature.Because of the bad environment begins the mutation of animals. Along the coast of Japan found a 50-pound squid. In Mexico, there was a mutation of a kangaroo. They have to have a dog's head, and large fangs. And in the Northern Urals began to die cattle. All these mutations have a negative impact not only on animals but on humans.Air pollution causes fluorosis in animals. This is a chronic poisoning caused by air pollution fluoride. Fluoride has also been detected in water and in food animals. Among the animals fluorosis affects sheep and cattle.Pasture contamination such compounds are a few factors. This is a natural soil dust, which is observed in some areas. This gaseous and dust waste companies, as well as the burning of coal. Today's enterprises, which produce enamel, cement, aluminum and phosphoric acid, contain fluorine compounds, including hydrogen fluoride.Animals in general are experiencing stress, when the parameters of the environment is changing dramatically. Even at a low level of pollution there comes the backlash against pollution. The reaction affects the molecular genetic basis of the body, showing features of ethology and the ontogeny of the animals, as well as changes characteristic of interspecific interactions.Radiation is also a negative impact on wildlife. During the testing of nuclear weapons into the air out the fallout. Radiation affects animals just like people. Fallout fall into the food. First, precipitation fall from the soil into plants and then accumulate and are consumed in food animals. At present, little is pollution, but information about the food consumed by the radioactive elements are not enough. Modern Further research is vital.Industrial and domestic waste water are subjected to mechanical, biological and physical treatment. Substances that are contained in the wastewater, is also negatively affect wildlife.The current environment, more and more has a detrimental effect on human and animal life. It is therefore necessary to preserve nature and animals. The organization promotes the preservation of nature reserves wildlife. Rare and endangered species are protected securely. In addition, reserves tame wild animals with valuable properties.Reserves are also involved in the separation of extinct animals, thereby enrich the local fauna
Problem atmosphere.
Even kids in kindergarten know that clean air is vital to us. But the modern state of the atmosphere, especially in large cities leaves much to be much better. Gas emissions of large enterprises now and then contribute to the spread is absolutely unfit for healthy living air that we breathe and our children. Save the deplorable state of the atmosphere can only greenery, but not everyone is interested to create, as they are taken away valuable space that could bring more profit.Expansion of green parks in the atmosphere will more than pure oxygen. And people will have even more space for recreation in the open. In addition to planting a variety of green plants and trees, you must also monitor the activities of all the chemical plants.Only strict control and the set limit the emission of harmful waste gas can prevent global air pollution and a sharp decline in the level of oxygen in the air.Many believe that the problem is not with respect to their environment the right way. But numerous diseases and pathology at the newly born children every day prove just the opposite.
