Does Being Around Trees Help People Feel Good?

Recent research has shown that trees clean the air, and our feelings. Trees are known to improve air quality by capturing six common air pollutants and toxic gases: ground-level ozone, particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide and lead. In fact, a single tree can absorb 10 pounds of air pollutants per year. Furthermore, being around trees can be good for mental health. In a study by Nature, researchers studied more than 30,000 residents of the Toronto, Canada area. They found that those who lived in areas with greater street tree density had a better perception of health than those who did not.
