Choose
one
of the following atmospheric issues: smog, global warming, ozone depletion, and acid deposition. Then, respond to the following:
y
What air pollutants combine and contribute to this issue?
y
What human activities produce the air pollutants in this issue? y
Briefly describe the health

environmental problems caused by the selected atmospheric
issue.
y
Provide at least one key solution to help either reduce the effects or recover from the effects of the selected issue.
Some air pollutants that have an effect on smog are generally any chemicals that are released into the air. Chemicals that are either released directly as a result of a person or natural occurrences, or other chemicals that is already in the air that reacts with chemicals that are released as a result of people or natural occurrences. Some human activities that produce these air pollutants include chemical plants and factories to make different products that release chemicals in the air. These chemicals are a result of the processes used to make the different items. Health problems caused by smog can vary depending on the person, but some issues include complications with asthma, breathing, and skin or eye irritation. An environmental issue that is associated with smog is air quality. A solution that could resolve this issue is to plant more trees and cut down on deforestation to help cleanse the air of the chemicals.
