This has to be one of the positives to come out of lockdown. If we take anything from the situation, let's have a cleaner environment.
Air pollution levels in the UK have dropped significantly in the weeks since the country went into lockdown.
The level of nitrogen dioxide (NO2) has fallen across the UK, with the daily average down by about 50% on the same period last year.
NO2, released from car exhausts, is a serious air pollutant.
Some cities have seen levels fall by more than 60%, including Brighton and Portsmouth, according to BBC analysis of Defra statistics.
