First national study finds trees saving lives, and reducing respiratory problems:

In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidences of acute respiratory symptoms. 

 

While trees’ pollution removal equated to an average air quality improvement of less than 1 percent, the impacts of that improvement are substantial. Researchers valued the human health effects of the reduced air pollution at nearly $7 billion every year in a study published recently in the journal Environmental Pollution. 

 

The study by Dave Nowak and Eric Greenfield of the U.S. Forest Service’s Northern Research Station and Satoshi Hirabayashi and Allison Bodine of the Davey Institute is unique in that it directly links the removal of air pollution with improved human health effects and associated health values.  The scientists found that pollution removal is substantially higher in rural areas than urban areas, however the effects on human health are substantially greater in urban areas than rural areas.

Yes trees are valuable in many ways. Pollution reduction, habitat for for wild life, support of mental health and health in general.....We just need more green spaces, in particular close to urban areas Reply

They found what one can expect and it is good to see the supporting facts: "in general, the greater the tree cover, the greater the pollution removal, and the greater the removal and population density, the greater the value of human health benefits.”

Trees planted along a city street screen residents from sun and noise—and from tiny particles that pollute urban air. Another recent study have shown that tree leaves can capture more than 50% of the particulate matter that’s a prime component of urban pollution and a trigger for disease. Reply

While the increase in vehicles is a part of urbanisation and can’t be prevented, we should combat this by increasing the green cover Reply
