This water is not clean, only looks clean. To claim that the water is clean you would need to show chemical analysis, not photos of a cormorant in a sunny day. Sun reflection can make anything blue, same as computer colour correction.

There are several problems with this photos. Problems in the blue hues for example. Many of those photos show an unnatural (slightly milky) hue of blue. If they analyze this water I bet that they will discover traces of bleach and maybe some methylene

The seaweeds shown are also a bad, not good sign. Its population will increase in the next months probably. Is a chinese invasive species that shouldn't be in Venice.

So I'm afraid that Not, nature will not reconquest Venice in two weeks. This is publicity.

:( why the negativity!? It's just clearer... Quote from the article: The apparent cleanliness of the water is not in fact due to a lack of pollution, said Davide Tagliapetra, an environmental researcher at the Institute of Marine Science. He told a local TV station that the reason is the absence of motorised transport, which normally churns up the muddy canal floor.
People know the water is still dirty. The point isn't that oh my it's been a week now it's perfect. The point is without large amounts of human waste the water is visibly better looking quality after a short time. And the fact it's amazing how much of an impact humans have on things.

Who cares if it is publicity, if it becomes a big things and raises awareness that's good.

Stop being so negative for no reason.

I'm grumpy. I know. The "stop being negative" mantra is a magical recipe to solve problems that rarely works. Understanding the problem is half of the solution.

> without large amounts of human waste

Venetia is directly connected with the mediterranean, a closed sea in a heavily populated and polluted area. Even if human waste will decrease in Venetia, the human waste created in Padua or Trieste will reach the coast and be redistributed again by tidal forces. Is unavoidable and nature will manage it.

So is probable that in a short term period the algae will rebloom to use all of the nutrients released by extraordinary coronavirus cleaning measures. I would not be surprised if a red tide event happens. Either that, or the sargassum will take all.

If Italians really want to improve nature in Venetia, they should be using this extraordinary grace period to do something about it. Something more than upload photos to instagram or twitter. Is an once in life opportunity.

Urg !? Why such a "negative-nelly" ? You ran outa T.P ?

The water looks "more clear" - There !
