Research on air quality by a team including Prof. Mathew Heal has been highlighted in the Guardian. The research shows that death rates have fallen over the last four decades as a result of reduced pollutants in the atmosphere.
However, the study authors also point out that more needs to be done. Prof. Heal is quoted as saying “People have to make sacrifices sometimes to fit in with legislation and it is good to tell the public that some of those sacrifices are having a benefit.”
