  1. 1. Ecology Project by Igoshina Margarita Centre of Education No.1408 Moscow2012
  2. 2. Sumatranian rhinoceroses are exposed to destruction! Earlier sumatranian rhinoceroses occupieddamp rainforests and swamps in Africa. Nowthese animals are on the verge ofdisappearance, only 6 populations remained.Decrease in populations of a sumatranianrhinoceros is caused first of all by illegalhunting for the horns, popular in the Chinesepseudo-medicine. Poaching threatens furtherexistence of this animals. Reduction ofpopulation of a sumatranian rhinoceros stillproceeds in current time.
  3. 3. Human expansion: manateesThe American manatee is an endangered animal. Despitethe fact that it has no enemies in nature, humanexpansion reduced its native habitat in coastal areas.Damages from screws of motor boats are put to manymanatees. Manatees swallow fishing tackles, and ascaffold, having got to digestive system of an animal startsto kill him.
  4. 4. Consumer relation ofpeople 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 pollutionThe Amur : fixed excess on phenol, nitrates andmicrobiological indicators are found in the river every year.As a result of the failure which occurred on November, 142005 on one of the Chinese chemical plants, there was amassed emission of poisonous substances to the riverSungary, as a result the spot of nitrobenzene, nitrogasolineand 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 waterdevice "Mir“ tests taken at immersion in July, 2010, showed that in ground deposits arounddumping 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 dioxinepollution exceeds that in northern and central parts of Baikal 40-50 times.
  7. 7. ааLake Pener –on Friday morning on November 21, 1980 the team of drillers conducted oilsearch under the lake bottom. During drilling the hole in the hydrochloric arch of the thirdlevel of the mine being near the lake on depth about 400 meters was punched. Under the lakethe hydrochloric mine settled down. Water quickly washed away a 35-centimetric opening andrushed down. In the lake Pener was created the huge whirlpool which has reached 55 metersin diameter. The lake is connected by the channel Delkambr being in 20 kilometers by the Gulfof Mexico therefore when Pener became grinds, the water level in Delkambra fell to meterand salty water began to flow in the opposite direction, filling the becoming empty lake. Theecosystem of the lake was transformed beyond recognition — fresh water replaced salty ofthe channel. Representatives of flora and fauna were replaced — there were sea types ofplants and animals. The maximum depth of the lake Pener grew in 100 times, having reached396 meters.
