“Work together”

These days in the US, it is risky to declare that “I APPRECIATE and RESPECT science and scientists.” Sharing that declaration is revolutionary. Join the revolution: listen to and take to hear the words of South Africa’s Dr Salim Abdool Karim: “We must work together"  (9:43 mins).
Dr. Karim is correct. But how to break through the mountains of prejudices burdening We the People?
Listen, too, to US’s Dr. Peter Hotez, Dean of the School of Tropical Medicine at Baylor College of Medicine, share the latest scientific information on Omicron (if impatient, skip to around minute 5:25 of this video clip (8:26 mins).
Advice: Don’t panic but be realistic about Omicron. Get the jabs, mask up, socially distance, go back to pandemic cautions of 2020. And urge your Congress person to ensure fresh vaccine is shared with Africa and Africans.

Healthy planet, anyone?

What, if any, links exist between Covid-19 and higher levels of pollution?
Scientists …looked for correlations between the disease and higher levels of pollution [and] found significant connections, but some worried that the available data, which averages groups of people, may hide other factors that were the true reason for the link.
So a new study this week  represents a major step forward. First, it used extensive individual data on almost 10,000 people in Catalonia and, second, it ran blood tests for coronavirus antibodies in about half of them. The testing is especially important as it identified people who had been infected but without symptoms. This group may have been missed in earlier studies.
The findings of this strongest study to date were striking: people exposed to moderately above-average levels of small particle pollution in the two years before the pandemic were 51% more likely to suffer severe Covid-19, meaning they were hospitalised. For those breathing higher levels of nitrogen dioxide, mostly produced by diesel vehicles, the increased risk was 26%.
This may well be because the dirty air had already damaged people’s immune systems or increased the level of heart and lung disease known to be a risk factor for severe Covid-19. Scientists can’t prove a causal link because, again, you can’t do harmful experiments on people.
Thanks to the blood tests, the researchers were able to show that air pollution did not significantly raise the chance of just being infected by coronavirus. It is likely that other factors such as social contacts, mask wearing and amount of travel are more important.

Our oceans make up more than 70% of our planet, and we have basically trashed them. The world dumps a jaw-dropping 17.6 billion pounds (8 billion kilograms) of new plastic into the oceans each year. Question: is cleaning up the oceans’ plastic an indisputably good idea…or is it more effective to stop making plastic
Good news:

The annual winter monarch butterfly migration, steeply declining in recent years, appears to be making a comeback. Biologists are encouraged and confused by the trend

Meanwhile, back at the ranch…

I continue to watch the news on Omicron and its effect on international travel. My intuition to wait before purchasing tickets was on the mark.
Last year, my agency and airline of choice – FlyUS and British Air – refused to refund the flights they cancelled due to Covid. Yes, I had travel insurance. Go figure. After a year of giving me the run around, they refused to refund me with a curt note. Live and learn: I’ll not fly using FlyUS or British Air again. I suggest you avoid them, too.
However, both airlines with whom I considered purchasing tickets this year are cancelling their flights to and from SA.
Giving thanks that I delayed purchasing tickets.
Watching and worrying about friends and family in SA (and US!)
