The first step is to learn about environmental problems. The cause of many problems is pollution. Plants and factories which produce things we need also pollute the air with poisonous gases, such as carbon dioxide. They also produce gases and substances which destroy the ozone layer of the atmosphere. It is dangerous, because this ozone layer protects the Earth from the space radiation. We can help keep this ozone layer, if we use ozone-friendly substances and sprays.
How to Protect Our Planet?
The protection of the environment is now the question of life on the Earth. Life on our planet needs special conditions. If these conditions are broken, there will be no life in a few decades. If we do not want to live in bad conditions, we must pay much attention to the problems of the environment.
The first step is to learn about environmental problems. The cause of many problems is pollution. Plants and factories which produce things we need also pollute the air with poisonous gases, such as carbon dioxide. They also produce gases and substances which destroy the ozone layer of the atmosphere. It is dangerous, because this ozone layer protects the Earth from the space radiation. We can help keep this ozone layer, if we use ozone-friendly substances and sprays.
The atmosphere pollution is also dangerous because of the greenhouse effect. It means that the climate becomes warmer and warmer every year. This is dangerous because it causes the melting of Arctic ice and the level of the Ocean can become higher. So, water will cover some land.
Another great problem is water pollution. Factories and plants produce water polluted with poisons or oils and let that water into rivers and seas. That is dangerous for the wildlife and for people. We need clean water to drink. There are also acid rains. They harm forests which produce oxygen. But we cannot live without oxygen. People must stop polluting water and do everything to help trees and other plants produce oxygen. People do a lot of things. They make special water and air purifiers and filters. They also organize National parks and Wildlife reservations. But many species of flora and fauna have died out, many are dying out now. I think that the best solution is to develop technologies which produce no waste.
I must also speak about the land pollution. Dirty water and fertilizers cause land pollution. Good plants cannot grow on the polluted land.
It seems that it is very difficult to stop pollution and all countries must work together to solve this problem. There is an international organization, called Green Peace which fights against pollution and protects Nature. But there are some ideas how every man can help nature. There are some alternatives to cleaners, pesticides and other substances which we can use, soda, for example. We should not cut trees and other plants, we should help animals. We must collect waste properly so it does not get into water or land. There is a good formula of RRR, It is Reduce, Reuse and Recycle.
We can reduce the usage of electricity and drinking water. For example, when you clean your teeth and let the water run, you lose two or three liters of water. Now multiply 3 liters by the number of people in our city and you will see that it is a lot. But we can stop it if we switch off the water. We can reduce the usage of packing and buying things in plastic packs. It is important, because it is very difficult to recycle plastic.
We should reuse everything we can. For example, we can reuse plastic bags. If people reuse plastic bags, the factories will produce less of them and will harm Nature less.
We also should recycle what we can. We can recycle paper, aluminum cans, glass and plastic bottles. I think throwing away and not recycling is a crime against our Nature! These things are very easy and every man can help a lot.
