Genuinely curious - is it really more clean though? Or is it just more visibly clear to humans (obviously, that is due to a reduction in pollution, but just how much?)
I'm just basing this thought off of waterways in Italy and such. When all the pictures of "unpolluted waterways" were going around... it's not that there was a drastic reduction in pollution. It's just that the silt hadn't been disturbed by boats/other man made things.
Very huge issue in diving - some famous cave divers have claimed that's typically the cause of their most near-death situations.

- kaybe 6y agoIt is, you can probably check the plots from your local air pollution measurements. (Of course, in isolation that means nothing since the values are influenced heavily by weather, eg wind direction, but in aggregate and in comparison to the past you can interpret it.) It is also especially obvious in satellite images (for those pollutants that can easily measured by satellite). Eg. the NO2 concentrations have gone down significantly in many areas of the world. eg. https://www.space.com/nasa-satellite-air-pollution-us-northeast-coronavirus.html https://www.space.com/nasa-satellite-air-pollution-us-northe... but you can easily look for more.
- nelaboras 6y agothe Dolphins in venice was really a matter oft cleanliness, and possibly less boat traffic. The canals aren't so deep that you would not see dolphins swimming through on normal days.
