All of our lives we have known that oxygen and air are the most precious resources to human beings. Human beings can survive for weeks or even months without food and for days without water. However a few minutes without air threatens our whole life. Today in the year 2050 air pollution is all around us and it continues to disturb the balance of nature and keeps on destroying the ecology of the world. We have endured many changes and adaptations. For how many years will we keep the planet earth going at this rate of pollution? We still don't have an answer to this question.
This problem began during the Industrial Revolution where changed agricultural and industrial practices created new chemical compositions (oil, coal, gas, carbon dioxide) and added gases that absorbed infrared radiation and were released into the atmosphere. As a result, the earth's atmosphere kept on changing and the temperature of the planet kept on rising and now the global warming factor has no solution. Because of that the greenhouse gases (carbon dioxide, methane, nitrous oxide) increased, resulting in the depletion of the ozone layer.
Due to these changes we can see significant regional variations around the earth. The sea level increased because of glacial melting. As a consequence many countries suffered flooding. The tropical regions lost their vegetation and this caused deforestation in the planet. The animals began to become extinct. In some places it didn't rain and the crops didn't grow. The hurricanes increased in intensity as a consequence of changes in climate. The water cycle that plays an important role in this natural process also was contaminated. It affected the vital cycle in the planet, changing the ecology of the earth.
Now in 2050, the nations of the world can do nothing because it is too late to save the earth. They didn't protect the environment when they should have. The chemical composition and pollution in the atmosphere are destroying all life on the...
