In the past few decades, our earth has undergone great changes, but among these changes, the air pollution caused by a large number of cars and coal is almost the most serious. The serious air pollution warns human beings that the production and use of automobiles have brought heavy burden to the earth. With the deepening of urbanization, more cars are needed, which will make air pollution more serious.
Therefore, we should first take the following actions: using the most advanced technology, using new energy to replace fossil fuels; secondly, striving to develop possible means of transportation. In short, our human beings should be responsible for air pollution, and we must find ways to solve this problem.
Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations can cause great damage. They can travel hundreds of miles in the wind and fall to the ground in the rain.
But this "chemical rain" will gradually destroy trees in the forest and kill fish in lakes in Germany. Trees in the country have been destroyed for more than a year, and serious accidents have polluted the air. A nuclear power plant in Russia has been polluted There was a serious accident at the station.
The radiation cloud swept across Europe. It is said that some people in Russia died because of the disease caused by the accident. A mass of dangerous gas enveloped the town of Bhopal.
Many people died that night, hundreds of thousands were injured and many of the injured were blind.
Air pollution air pollution is one of the main problems in the modern world. Factories in modern industrial countries need a lot of energy. Cars, trains, airplanes and buses all need energy.
Almost all of these energy are generated by burning fuel. Combustion will produce waste, some of which will remain in the air, causing air pollution. Scientists are looking for ways to prevent air pollution Methods, especially in large industrial areas and densely populated cities, they are studying new ways of generating electricity to reduce environmental damage.
At the same time, many power plants are being modernized to release less polluting substances. Engineers are trying to design and locate new power plants to minimize the damage to the environment. Maybe we still have a long way to go before we can have a "clean" world.
Almost all countries are trying to prevent and control air pollution. There seems to be no end to what environmentalists have to do. People will constantly look for new ways to control pollution.
