  1. 1. Ecology Project by Igoshina Margarita Centre of Education No.1408 Moscow 2012
  2. 2. Sumatranian rhinoceroses are exposed to destruction! Earlier sumatranian rhinoceroses occupied damp rainforests and swamps in Africa. Now these animals are on the verge of disappearance, only 6 populations remained. Decrease in populations of a sumatranian rhinoceros is caused first of all by illegal hunting for the horns, popular in the Chinese pseudo-medicine. Poaching threatens further existence of this animals. Reduction of population of a sumatranian rhinoceros still proceeds in current time.
  3. 3. Human expansion: manatees The American manatee is an endangered animal. Despite the fact that it has no enemies in nature, human expansion reduced its native habitat in coastal areas. Damages from screws of motor boats are put to many manatees. Manatees swallow fishing tackles, and a scaffold, having got to digestive system of an animal starts to kill him.
  4. 4. Consumer relation of people to elephant turtles After discovering Galapagos archipelago Europeans elephant turtles began to be used by sailors as «live canned food» — they placed in holds alive, where they could be on several months without water and food. Now we can see from records of logbooks, only 79 whaling vessels took out from the archipelago about 10.373 turtles during 36 years. It is considered that about 200.000 elephant turtles were destroyed during the XX century. They disappeared completely on Charlz and Barington islands , and almost died out on others islands.
  5. 5. Environmental pollution The Amur : fixed excess on phenol, nitrates and microbiological indicators are found in the river every year. As a result of the failure which occurred on November, 14 2005 on one of the Chinese chemical plants, there was a massed emission of poisonous substances to the river Sungary, as a result the spot of nitrobenzene, nitrogasoline and other chemicals moved on a current to the Amur.
  6. 6. The lake is in danger! Lake Baikal In 1966 production on the Baikal pulp and paper mill began. The results of the deep water device "Mir“ tests taken at immersion in July, 2010, showed that in ground deposits around dumping of drains of the Baikal pulp and paper mill, there are high contents of the dioxine, which is dangerous poison for any live organisms. Around the pulp and paper mill dioxine pollution exceeds that in northern and central parts of Baikal 40-50 times.
  7. 7. аа Lake Pener –on Friday morning on November 21, 1980 the team of drillers conducted oil search under the lake bottom. During drilling the hole in the hydrochloric arch of the third level of the mine being near the lake on depth about 400 meters was punched. Under the lake the hydrochloric mine settled down. Water quickly washed away a 35-centimetric opening and rushed down. In the lake Pener was created the huge whirlpool which has reached 55 meters in diameter. The lake is connected by the channel Delkambr being in 20 kilometers by the Gulf of Mexico therefore when Pener became grinds, the water level in Delkambra fell to meter and salty water began to flow in the opposite direction, filling the becoming empty lake. The ecosystem of the lake was transformed beyond recognition — fresh water replaced salty of the channel. Representatives of flora and fauna were replaced — there were sea types of plants and animals. The maximum depth of the lake Pener grew in 100 times, having reached 396 meters.
