Plant growth might be stunted worldwide by the end of this century due to air pollution, a new report concludes.
Mounting ozone concentrations resulting from pollution will damage plants and block them from taking up the invisible, odorless gas that gives them life, the thinking goes. The change would occur despite the carbon dioxide boost to greenery that some have said global warming will provide.
As a result, carbon dioxide concentrations would build up in the atmosphere even more than expected, the study researchers say.
