According to Taking A Stand Against Environmental Pollution by Newton, most of the substances that are harmful are: carbon monoxide and a variety of complex hydrocarbons and nitrogen oxides. ... Consequences of Pollutants Carbon dioxide may reach a capacity in the atmosphere that it may exceed the capacity of the plant life to remove it. In the atmosphere, an excess of carbon dioxide creates a greenhouse effect. An increase in carbon dioxide causes an increase in the temperature all over the world. ...
