In truth, we wish masks worked. If they did, it would be a cheap, and easy way to control the spread of Covid.

UNEP's new Human Development Index includes a new (separate) index: Planetary pressures-adjusted HDI (PHDI). News in Norway is that its position drops from #1 to #16 because of this, while Ireland rises from #2 to #1.
Why?
https://t.co/aVraIEzRfh
Check out Norway's 'Domestic Material Consumption'. Fossil fuels are no different here to Ireland's. What's different is this huge 'non-metallic minerals' category.
(Note also the jump in 1998, suggesting data problems.)

In Norway's case, it looks like the apparent consumption equation (production+imports-exports) for non-metal minerals is dominated by production: extraction of material in Norway.
https://t.co/5QvzONbqmN
And here we see that this production of non-metallic minerals is sand, gravel and crushed rock for construction. So it's about Norway's geology.
https://t.co/y6rqWmFVWc
Norway drops 15 places on the PHDI list not because of its CO₂ emissions (fairly high at 41st highest in the world per capita), but because of its geology, because it shifts a lot of rock whenever it builds anything.

An interesting thing about carp is that they can go into anoxic hibernation and switch to an anaerobic metabolism based on converting glycogen to ethanol.
The waste ethanol is diffused out the gills

Carp can switch over to an anaerobic metabolism and quietly exhale booze until the situation gets better.
They basically evolved the same metabolic pathway as yeast, independently.
In theory, if you spent a few thousand years breeding carp for it, you could use them to make booze.
They'd be enormous, almost entirely glycogen deposits with a fish added as an afterthought.
The really interesting thing about anaerobic carp, is that they can go 4-5 months without oxygen by relying on liver glycogen.
You, a human, have only about 100 grams of glycogen in your liver, about 400 more grams in your skeletal muscles. Call it 500 grams total.
In humans, glycogen is also burned for energy. This is where the marathon runner's bonk comes from: you only have about 2,000 calories worth, and running a marathon burns those 2,000 calories.
