ENVIRONMENT
Many people believe that the way we live our lives today is having an extremely bad effect on the environment. Here are some examples of environmental problems and solutions.
Pollution – is damage to the air, sea, rivers, or land caused by chemicals, waste and harmful gases. Pollutants include toxic waste, pesticides, and fertilizers.
environmental problems:
Cars – the biggest polluter today is the car. Exhaust fumes are the main cause of bad air quality, which can make people feel ill and have difficulty breathing. This problem is especially bad in some cities where, on days when there is not much wind, a brown layer of smog hangs in the air. The number of cars is increasing every year, and this causes serious congestion. Governments then build new roads to try to improve the situation, but this means that they cut down trees and destroy more of the countryside.
The GreenHouse Effect is caused by harmful gases known as greenhouse gases. These gases are produced when we burn fuels, especially coal burned in power station to make electricity. The gases go up into the Earth’s atmosphere and stop heat from leaving the Earth.
Because the heat cannot escape, the Earth is getting warmer. This is known as global warming. Global warming may cause the ice at the North Pole and South Pole to melt and sea levels to rise, leading to serious flooding in many parts of the world. In other places, temperatures will ride and there will be less rain, turning more of the land into desert.
Hole In The Ozone Layer. The ozone layer is a layer of gases that protects us from ultraviolet light from the sun, which can have a harmful effect on animals, and causes skin cancer in humans. The ozone layer is being damaged by chemicals, especially chloroflourocarbons, and when holes appear in the ozone layer, harmful light from the sun reaches the Earth.
