Nature might be better than tech at reducing air pollution

According to a study, planting native vegetation could cut air pollution and costs.


According to a story from Ohio State University, new research has shown that plants surrounding factories and other buildings that produce pollution could significantly reduce pollution in the area.

Per the story, below:

Adding plants and trees to the landscapes near factories and other pollution sources could reduce air pollution by an average of 27%, new research suggests.

The study shows that plants — not technologies — may also be cheaper options for cleaning the air near a number of industrial sites, roadways, power plants, commercial boilers and oil and gas drilling sites.

In fact, researchers found that in 75% of the counties analyzed, it was cheaper to use plants to mitigate air pollution than it was to add technological interventions — things like smokestack scrubbers — to the sources of pollution.

 “The fact is that traditionally, especially as engineers, we don’t think about nature; we just focus on putting technology into everything,” said Bhavik Bakshi, lead author of the study and professor of chemical and biomolecular engineering at The Ohio State University.

“And so, one key finding is that we need to start looking at nature and learning from it and respecting it. There are win-win opportunities if we do — opportunities that are potentially cheaper and better environmentally.”

The study, published today in the journal Environmental Science & Technology, found that nature-based solutions to air pollution might, in many cases, be better than technology at combating air pollution.
