How can we save our planet?
Pollution of our planet is one of the biggest problem our civilization. Technical Progress is a kind of paradox because developing industry more and more polluted environment, on the other hand the newest inventions can be environmentally-friendly. In my speaking I want to present how can we save our planet.
First I tell a few words about atmosphere. The main coused of polutted atmosphere is carbon dioxide and other waste gases like CFCs. Most of petrols contain lead which is a very poisonous. Those gases are getting in to the atmoshopere from factories, motor vehicles or power stations. Those pollution couse the greenhouse effect, global warming, holes in the ozone layer or acid rains. We can stopped this process by fit a filters on chimney stack, use unleaded petrol, use aerosol cans and fridge which are marked “ozone friendly".
The next problem that I want to present is water pollution. Acid rains, industrial waste from factories, chemical fertilizers and pesticides use by farmers are the major couse of water pollution. It kills fish in rivers and lakes. We must stopped it because a lot of water animals become extinct. The water is very important for us because about 70% of the human body is water. We have to build new waste-water treatment plants, save water in our households and bring close circulation of water in factories.
The last problem that I want to present is soil pollution. When we are cut down or burned forrest the soil is washed away, so that area may turn to desert. When we will use more and more fertilizers the soil will be jejune. Next, the farming couldn't develop and in the world will be more hunger. We have to use natural fertilizers but only in not large quantities, don't use pesticides and don't cut down and burned forrests.
That is only a few simple ways how we can save our planet and if we start use it our planet will be healthy.
