Question 5

-Many of the chemical hazards in our world can be avoided by lifestyle choices. However, air pollution, which is the fourth leading cause of death worldwide, is a form of chemical hazard that we do not have direct control over. Sandra Steingraber, in her book "Living Downstream," discusses the idea that clean air should be elevated to the status of a civil right in the United States. What would have to occur in order to have clean air become a civil right? Does not having clean air prevent you from realizing your other civil rights? If it were a civil right in the United States, would this guarantee clean air for you as a citizen of the U.S.?

Accepted Answer

In order for clean air to be elevated to
