Answer 2

Step-by-step explanation:

Environmental Pollution influences the quality of nature’s life more than one can assume. It acts in unnatural ways, sometimes which cannot be viewed by the open eye. Though, it is very much existing in the atmosphere. For example, you might not be capable to see the natural gases (oxygen, Carbon-dioxide) present in the air, although they are still existing. Furthermore, the pollutants which are slaughtering the air and raising the levels of carbon dioxide are very critical for humans. Raised levels of carbon dioxide will lead to global warming.
