The coronavirus
pandemic has had an unexpected side effect in Venice, where the
normally cloudy canals have transformed into water crystal clear enough
to see fish swimming below.
Italy's tourism industry came to a screeching halt once the number of coronavirus cases began to spike in the country, but those who remain have been posting to social media images of the traffic-less canals. However, the transparent water isn't so much a sign of better water
quality as it is the result of the lack of boat traffic, which typically
kicks sediment to the surface, Pierpaolo Campostrini, the managing
director for the Consortium for Managing Scientific Research on Venice
Lagoon System, told ABC News via email."The low turbidity of the water does not mean cleanliness," Campostrini
said. "The transparency is due to the absence of sediment resuspension."
The cold temperature of the water also plays a part, Campostrini said.
At about 57 degrees Fahrenheit, there is little synthesis of organic
compounds from carbon dioxide, which doesn't begin until about 62
degrees Fahrenheit.
It's likely that the air quality has improved
since "every kind of pollutants decreased a lot," but a chemical
analysis would need to be performed to say so for sure, Campostrini
added.
Amid the crisis, the clear water is a small reprieve for Venice, which just months ago experienced flooding by the highest tide in more than 50 years, causing inestimable damage to the centuries-old city.
More than 35,000 coronavirus cases have been confirmed across Italy, the
second-highest national total behind China, according to data compiled
by Johns Hopkins University's Center for Systems Science and
Engineering. https://abcnews.go.com/International/venice-canals-clear-fish-coronavirus-halts-tourism-city/story?id=69662690
Tracking U.S. COVID-19 Vaccine Donations Published: Sep 22, 2021 https://www.kff.org/coronavirus-covid-19/issue-brief/tracking-u-s-covid-19-vaccine-donations/ Facebook Twitter LinkedIn Email Print There remains a significant gap in vaccine access across the world, with only 2% of the population in low-income countries (LICs) receiving at least one vaccine dose, compared to 30% in lower-middle-income countries (LMICs), 54% in upper-middle-income countries (UMICs), and nearly two-thirds in high-income countries (HICs). One way to address this gap is for countries that have vaccines to donate them to countries in need, either via the multilateral COVAX mechanism or directly to countries and/or regions via bilateral donations. For its part, the U.S. government has pledged to donate at least 1.1 billion doses of COVID-19 vaccine for global use by 2022 and has been delivering doses to countries around the world since June. 1 To understand more abo...

Experts can’t agree The World Health Organization says the evidence is not compelling, but scientists warn that gathering sufficient data could take years and cost lives.

KKM hide cases in PPV. There are 2 more cases at PPV in Sabah, but not reported by KKM. Only investigate. We must sue KKM for being reckless. One in Telupid was reported in the news but KKM did not even investigate. Another case in Kota Kinabalu, was posted in facebook, even with test result, but KKM only investigate but so far no news. KKM only denied asking people to get tested, which I suspect was issued by one of KKM staff unofficially. If it can happen to 2 cases in Sabah, imagine the situations in Selangor. I suspect many of them catch Covid at the PPV, but no record of any cluster, just as KKM hid the clusters at factories to the point that Azmin presented the fake data to Parliament. As is normal in Malaysia, authorities never learned that hiding one or two cases means that the cases are widespread and to be safe, we must assume that it happens to all places. All PPV in Malaysia are infected with the Delta variant. Notice that the Delta variant only needs 15 seconds of exposure...
