Exercise 2
1. Acid Rain 2.Animal in Danger 3.Soil Erosion 4.Ozone Hole

  • a)

  • Perhaps the most famous rare animal is the panda. 25 years ago it was nearly extinct. Now, its numbers are growing again. It’s even become a symbol for wildlife conservation. But many other animals have been less lucky than the panda. This is because man hunts them , destroys and pollutes their habitat.

  • PANDANING RASMI

b)……….

  • This happens when gases and chemicals mix with water in the air. The mixture travels for hundreds of kilometers and finally falls back to the earth. Because “acid rain ” contains a lot of chemicals, it kills fish and trees. It is also attacking many of Europe’s most famous buildings-Notre Dame in Paris and St Pail’s Cathedral in London. Research shows more lung and kidney illness in countries with high levels of acid pollution.

c)………………..

  • CFC gases are in aerosols , refrigerators and plastic boxes. CFC molecules are very dangerous. Each one can trap 10000 times more heat than a molecule of carbon dioxide. And they don’t just stay in the air – they destroy it. Because of CFCs, the top level of the atmosphere (the ozone layer) is now getting thinner. This ozone hole allows more of the Sun’s rays to get to the Earth and this can cause skin cancer and weaken people’s immune system.

d)………………

  • People used soil year and so it became poor and thin. They cut down many trees. Many people raised goats that ate all the vegetation. This is how the Sahara desert appeared. Everybody knows that rainforests are the lungs of the earth, but still 42 million acres are cut every year.

  • Darahtlarning kesilishi rasm
