Essay
Air- it's fundamental factor of life on the earth.Thanks to the air-we can lead a normal life.However, with everyear, we somehow influence the air.
People on the Earth-it is catastroph for the Planet, because we impact on the nature in negative way,and air- is not an exception.Due to industrial human activities,we polute the air more and more.when industrial plants are running, they have emissions and these emissions pollute the air.If think carefully-air is one of the most essential thing on our Planet, but we treat him with disdain, and it makes me upset.due to the fact that we ourselves pollute the air, this also makes us bad, for instance a lot of diseases caused by air pollution.
We need to treat air and environmental problems with respect, because they give life on the planet!
