Corona's positive ecological side-effect

A friend just told me that dolphins were spotted in the port Cagliary and the canals of Venice are becoming clear as the water is receiving a lot less pollution and traffic due to the corona quarantine. I'm not sure how much of this is true, but it's certain that pollution levels are much lower now. China reported to have 20% less nitrogen greenhouse gasses, and I'm sure Europe is seeing a lot better air quality as well (Euros like their cars...).

Greece is afraid the tourist season is going to be bad; the minister is still optimistic (or naive) as he believes we all crawl back into overcrowded airplanes full of coughing people and also missed that the people in quarantined countries are now burning up their hard-earned holiday-money.

So for Greece's sea this virus might actually be very beneficial. One summer without 5 million tourists per day asking (demanding) for fresh fish can rebounce fish stocks quite a lot. This is just one example of nature getting a break. Many more examples could be listed here.

- What are your opinions/forecasts on this? How about the other countries?
- How can we use this in our advantage, as (free-)divers and as world, both ecological and economical?
- ...?

Personally I'm not interested in this because 'maybe we can shoot more groupers in the face'. I hunt for food, not sport, and as long as there is lionfish around here I eat lionfish. The only use my speargun sees at the moment is for hunting some rabbitfish, another invasive and damaging species around here.

But I hope that should the positive effect of this on nature be visible, that we will learn from it. I'm afraid we don't. That's why right now this should be discussed everywhere, as when this is over we all go back to buying crap we don't need and working jobs we hate and we would have missed a great oppertunity.

Another example of how this situation is teaching us alternatives to our normally very damaging lifestyle is the work-from-home a lot of people are doing at the moment. My brother works on a university and now teaches his classes using skype. He told me it's actually going *really* well, while a months earlier he was part of the voice saying that remote teaching would be nearly impossible.

I imagine the first week of a world without oil would look not much different than this. So we're getting a free training here.
