History shows us a disappointing trend. Human is the main enemy of the environment. Just in the last few decades the result of technological progress made irreparable damage to the environment. The global ecological catastrophes are especially harmful for the biosphere.

In the 20th century environmental disasters occur with alarming regularity. Their main danger is that the effects of each of these incidents will be felt for years. Consider the list of the largest environmental catastrophes that have significantly changed our world...

The disaster in Bhopal

The disaster in Bhopal (city in central India) is one of the most deadly environmental disasters in the world. December 3, 1984 was an accident at a local chemical plant. As a result, into the atmosphere was thrown 42 tons of toxic chemicals - methyl isocyanides. A cloud of poison instantly covered the nearby slums and railway station. Fatal role in the scale of the tragedy played a high population density, lack of qualified staff and the wind, which carried the chemical rapidly around the city. In just a few hours 4000 people were killed. Another 14,000 died in subsequent years from chemical poisoning. The exact cause of the tragedy, despite the numerous proceedings cannot be called until now.

Chernobyl disaster

There were no signs of trouble one day in April 1986 in Chernobyl. People enjoyed the first rays of the sun in the open air, without even knowing that their lives were in great danger from the radiation. April 26th the fourth reactor Chernobyl exploded. According to official data of that time, 31 liquidator of accident died as a result of the explosion and subsequent fire. However, publicity of the 90s has given access to the data, which have plunged the world into shock. The Chernobyl accident is recognized as the most destructive of its kind. Тhe liquidation for several years involved more than 600 thousand people. Victims of radiation were calculated by tens of thousands. Vast territories in Europe had been contaminated with radioactive substances. The Chernobyl nuclear station worked as a "dirty bomb", the most powerful and the most destructive. It is worth noting that the scale of the long-term impact of the disaster on the environment debate so far.

The explosion of an oil platform in the Gulf of Mexico

Deepwater Horizon is a major oil platform that worked in the Gulf of Mexico. In April 2010, an explosion occurred on it due to technical problems. It has caused irreparable consequences. Within 152 days rescue workers from around the world have been unable to stop the leakage of oil. The platform sank. To this day, the experts cannot identify the volume of fuel that was spilled into the waters of the bay. However, it is estimated that as a result of the monstrous disaster 75 thousand square kilometers of water surface was covered with thick oil film. The strongest environmental damage experienced US states that are adjacent to the Gulf of Mexico: Alabama, Mississippi, Louisiana, and Florida. Coast was literally strewn with the corpses of sea animals and birds. More than 400 species of rare animals, birds and amphibians were on the verge of extinction. There has also been recorded outbreak of mass deaths of marine mammals within the Gulf, particularly cetaceans.

The death of the Aral Sea

The Aral Sea which is, in fact, a lake was once considered the fourth largest lake in the world. In the 60s of the last century development of the surrounding fertile land was started. Uncontrolled pumping of water for agriculture in favor of the ambitions of the Soviet leadership led to tragic consequences. Lake was completely dried up for 50 years. Refill with fresh water was not commensurate with the volume of pumping. Instead of a natural reservoir now there is a large salt desert Aralkum. Dozens of species of animals and fish were killed; the local climate is changed; the region is almost empty. The bottom of the former lake bed is covered with pesticides that were widely used in agriculture. The consequences of environmental disaster are still being felt. With strong sand storms, these particles are spread over hundreds of kilometers, and continue to destroy nature and its inhabitants.

London Smog of 1952

London is famous for its fogs. The locals are so used to them that the one that enveloped the capital of Britain on Dec. 5, 1952, did not initially alert anyone. However, gradually the weather conditions deteriorated and the city started to panic. The movement of public transport stopped; public places were closed; ambulance stopped. Smog, which consisted of particles of waste coal dust, sulfur dioxide, exhaust, settled over the city due to adverse weather conditions. The fog was very dense. He covered the city for about 4 days. During this time, the cases of respiratory diseases, in particular bronchitis, pneumonia became more often. This led to mass deaths. Modern calculations confirm the death of about 12 thousand people.

Knowledge about the environmental disaster and what they produce must teach a person more careful treatment with the environment. However, contrary to common sense, people mindlessly continue to destroy their own home.
