Why cities should plant more trees (Video)

This video looks at a more global perspective to identify regions that would most benefit from trees to combat air pollution.

We did a similar calculation locally to target areas most in need of trees (higher than average air pollution levels + lacking street trees) and with the invaluable cooperation of the city of Hamilton's forestry department, local councillors, neighbourhood hubs, and OPIRG McMaster, we've had five great summers of success.

Check out the video to find out how trees help clean the air.
