Swings and a Small (but Suggestive) Roundabout?

A modelling study has suggested that Europe has seen 11k fewer deaths attributable to air pollution over the Covid-19 lockdown (https://www.theguardian.com/environment/2020/apr/30/clean-air-in-europe-during-lockdown-leads-to-11000-fewer-deaths). Although this is only a fraction of the deaths (more than 200k) produced by the virus, one also should note that there have also been fewer people developing long-term respiratory illnesses (like asthma) so the health gains may well be higher. It would be a good move if this was remembered as we move out of lockdown. We should try to improve health as a matter of course.
