Environmental problems. Air, Land and Water Pollution Destruction of the countryside beauty Deforestation Destruction of ozone layer Endangered species Nuclear pollution Overpopulation
Ozone Layer It protects the Earth from ultraviolet radiation Sprays and chemicals destroy the ozone layer Factories produce carbon dioxide These have formed a blanket around the Earth These blanket traps the heat of the sun. The Earth is getting warmer.
Acid Rain Acid rain is caused by cars and lorries, factories and electric power plants that use fossil fuels. When fossil fuels are burned they release gases called sulphur dioxide and nitrogen oxide into the atmosphere. This gases mix with water to form clouds of dangerous acids. It is highly acidic and causes a great deal of damage to our planet.
Greenhouse Effect It works like this : sunlight gives us heat. Some of the heat warms the atmosphere, and some of the heat goes back into space. Nowadays the air surrounding the earth has become much warmer because the heat can’t go back into space. That’s why winter and summer temperatures in many places have become higher.
Deforestation Every year over 100000 sq. km of forests are so badly damaged that they will hardly be able to recover. Paper and cardboard, both made from wood. If we go on like this, by the time you are as old as your grandparents are now all the forests on earth can be destroyed. This includes rainforests in South America, Africa and Asia. The huge forests help to control the world’s weather and to produce much oxygen in the air.
Endangered Species People’s activities destroy animals and birds’ habitats. Because of noise in big cities and airports they can’t breed their youth. We pollute seas, forests and other places where animals and birds live. Because of using pesticides we poisonous food animals and birds eat. People hunt animals and birds for fur, teeth skins and just for pleasure.
Endangered Species Nearly 25000 species of plants, more than 1000 species of wild animals have disappeared. Why? A man kill animals and birds for pleasure and money.
Air Pollution Will it be possible to breathe without breathing masks in the nearest future? Dust particles from industrial chimneys Carbon dioxide is the result of coal-fired power stations Burning things Exhausted gas from cars Smoke factories produce
Reduce Try to reduce the amount of rubbish we throw away The less we throw away, the more we help the environment
Reuse Don’t grow clothes which your kids have grown out. Live them for charity Use plastiс bags from supermarkets again
Recycle Glass, newspapers, magazines, plastiс- they can all be recycled.
THE EARTH IN OUR HANDS Hundreds of thousands of roots and shoots, hundreds of thousands of young people around the world, can break through walls. We CAN change the world. Dr Jane Goodall (environmentalist, humanitarian and biologist)
