С древних времен, природа продлевала жизнь человеку, снабжая его ресурсами для жизни. На протяжении тысяч лет, люди жили в гармонии с окружающей средой и им казалось, что богатства природы неисчерпаемы. Но с приходом цивилизации человека, катаклизмы в природе начали увеличиваться.
Каждый год мировая промышленность выбрасывает в атмосферу около 1000 миллионов тонн пыли и других веществ. В результате некоторые редкие виды животных, птиц, рыб и животных исчезли навсегда. Многие города страдают от смога.
Since ancient times Nature has served man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited. But with the development of civilization man’s interference in nature began to increase.
Every year world industry pollutes the atmosphere with about 1000 million tons of dust and other things. As a result some rare species of animals, birds, fish and plants disappear forever. Many cities suffer from smog.
Large cities with thousands of smoky industrial enterprises appear all over the world today. The by-products of their activity pollute the air we breathe, the water we drink, the land we grow vegetables.
Stop! Enough to pollute the environment! If you want to live in a clean and breathe normal air, first take care of yourself: do not throw trash on the street, because at every corner there are trash when people understand this is what the world will be much cleaner. And if you think: «that that is really there, I'll throw a little wrapper, nothing will happen», and so everyone will think. So much pollution.
The pollution of air and the world’s ocean, destruction of the ozone layer is the result of man’s careless interaction with nature. Environmental protection is of a universal concern. That is why serious measures to create a system of ecological security should be taken.
But these are only the initial steps and they must be carried onward to protect nature, to save life on the planet not only for the present but also for the future generations.
