From a volcano, per the source you linked:
"The Hunga Tonga-Hunga Ha’apai volcano — which violently erupted in January 2022 and blasted an enormous plume of water vapor into the stratosphere – likely contributed to this year’s ozone depletion. That water vapor likely enhanced ozone-depletion reactions over the Antarctic early in the season.
“If Hunga Tonga hadn’t gone off, the ozone hole would likely be smaller this year,” Newman said. “We know the eruption got into the Antarctic stratosphere, but we cannot yet quantify its ozone hole impact.”
As long as they don't let it be run by private equity firms like the US. In theory our combination long term care/short term rehab facilities provide this care model. They contain a doctor, nurses, aides, social workers, and physical therapists. Who are all paid rock bottom wages and criminally understaffed while the owners rake in millions by literally bankrupting vulnerable elderly people.
I'm assuming the UK facilities will be public like NHS unless the Tories get their way and kill that too.
