That trust was shaken the other day when they said "daddy did you know you shouldn't sleep under trees because you can't breathe properly?" I'm like who told you that. "A video."[1]
Turns out it was a "learning" video produced by one of these outfits, not ChuChu but a competitor called AumSum. It's some weird urban myth that has traction in south asia.[2] It's a bastardization of tree respiration biology. They think it puts out enough CO2 at night to impact humans. So don't sleep near it because then you'll be oxygen deprived.
So yeah, apparently someone green-lit that stinker and turned into a cute animation. Which is funny until you realize AumSum as a whole has 139M views. Their singular mission is to make educational science videos.[2] And my kids are 100% addicted to YouTube Kids.
