kitten corner: you'll never learn
apparently, no lesson is sufficient nor sufficiently recent
i don’t mean to be a cassandra kitty or anything, but i think probably that if you put a big red button on the wall marked
“WORLD EXPLODES IN FIREY CATACLYSM BUTTON, DO NOT PUSH”
that humans would basically walk right up and say “huh, i wonder what this does?” then push it…
seriously, what is it with you guys?
For once, this is clickbait. We've always known that Yersinia pestis was the main cause of bubonic plague. Also, it's not a virus, it's a bacterium spread by fleas, so it's readily controlled with pesticides (to stop the fleas) and antibiotics (to stop the pathogen).
Did they wear masks while doing so? If so - all is ok. Especially those cloth ones from Walmart.
