A good charity would be able to get the most out of your money. At least you know the chances of your $20 turning into drugs, alcohol, or gambling is minimal that way.
Making money takes time and effort, and you owe it to yourself to see it spent wisely.
Just using some tiny mammoth population on an isolated island in Siberia to state "MAMMOTHS WERE STILL ROAMING THE EARTH WHEN BLAH BLAH BLAH" is somewhat disingenuous.
I don't remember this episode of Beastars, but it looks great.
