planting a tree

Explanation:

Human activities can impact air quality in many different ways. Some activities harm air quality and some activities improve it.

Planting a tree is one way to positively affect air quality. Trees improve air quality via photosynthesis and can filter some pollutants out of the air.

Activities that can harm air quality include clear cutting a forest, flying a jet airplane, and driving a car. Damaging forests decreases their ability to improve air quality. Flying jet airplanes and driving cars releases pollutants into the air.
