Air is one of the most important elements of the environment for our existence. It is a natural gift and a free resource. The air is polluted in various ways. Ground vehicles use fuel and oil, which create smoke.
The smoke mixes with the air and thus pollutes it. Factories and factories are also responsible for air pollution as they also generate smoke.
Obviously air is essential for every life being on our planet — for people, animals and plants. Without air no life on Earth could exist. But today we face one urgent problem — the industry keeps on developing and it results in air pollution. There are so many factories around that exhaust wastes into the air.If you live in city you have certainly noticed how hard it is to breath sometimes. This happens because of huge amount of cars and their exhausts. In some countries there is even a law that allows families to have only one car to reduce the amount of harmful substances that they throw into the air.Why is air pollution so dangerous? Of course the first reason is that we need fresh air to breathe. Another reason is greenhouse effect. Around the Earth we have an ozon layer which saves us from the harmful effect of ultraviolet radiation. All the wastes we throw into the air destroy the ozon layer and more radiation penetrates into the atmosphere. Consequently, the air becomes hotter and this is called greenhouse effect which results in global warming. Why is global warming dangerous? It causes ice to melt and this can lead to world flood.
