I am concerned that Mayor Ralph Becker's approach to clearing Salt Lake City's air is not looking at the simple solutions which cost less and make more sense.
First, he is overlooking the huge impact that adding trees to our city will effect. Although the city has many trees, adding trees will cool the city and clean the air. Two medium-size trees will provide enough oxygen for a family of four for one year, according to the University of Maryland.
Trees also lock up carbon from the atmosphere. The water we use to sustain them is a small price to pay for all the good they do.
