Air pollution is the presence or introduction of a substance which has harmful or poisonous effects to humans and other living organisms in the air . Poor air quality is a substantial subject in today's society. Exposure to bad air quality increases risk of numerous health risks like respiratory infections, lung caner, and heart disease for example.  I chose this topic because I believe that this is an environmental issue that ties into almost any aspect of everyday life, therefore crucial to all of civilization to change.                                                                                                                                                                                                                                                                                                                                                                                                    “Water and air, the two essential fluids on which all life depends, have become global garbage cans.”
