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.
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.
Limiting flights would be silly. That's an input, not an output. If we want to limit CO2 (and other greenhouse gasses) then we need a global emissions tax or cap and trade system.
How effective is that, I am wondering? My concern is that any tax that ends up as a cost will affect passengers and higher prices. Will that stop people from flying more? I dont' know. I know too little about this.
But you know and what you think is silly may be effective and better in the long run. We need more 'silly' ideas in order to find a good one. In contrast, you can't have unlimited flights either, where the toughest and most powerful airline can fly the most just because they can cope with high taxes. That would only favour the big airlines.
We see that this virus has been really effective in lowering emissions. We're talking about changing human behavioural patterns deep within, I don't think taxes can create such a strong force.
What do you mean by trade system? Not sure I understand that.
>we in the future see politicans limiting number of aircrafts / year
I get that this is a limitation you agree with, but if you agree with the idea of politicians limiting things people want (flights and travel are things people want!), remember you won't get much sympathy when they will use it to limit something you want. Everything we do is somebody's pet cause.
I think the GP comment is saying that there’s just a one-dimensional slider, “allowed amount of government intervention”, and you don’t really get to decide what form that intervention takes.
