Plants better than tech for reducing air pollution

Plants and trees may be better and cheaper options than technology to mitigate air pollution, says a new study from an Indian-origin researcher.

The study, published in the journal Environmental Science & Technology, found that adding plants and trees to the landscapes near factories and other pollution sources could reduce air pollution by an average of 27 percent.

Researchers found that in 75 percent of the countries 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.
