A kid was hurt by these cyanide mines and it also killed his dog https://amp.idahostatesman.com/news/local/environment/article217956755.html
Reading this I figured "must be some fucked up thing they're recently trying in a single state" but holy fuck, they've been in use since the 1930s - and the previous version at least has killed many people. And the new version has injured at least one kid and killed tens of pets.
Australia is apparently now using them too. It is, indeed, completely insane.
The ones in Australia don't use cyanide.
They're loaded with 1080, a poison which is far more lethal to invasive species than indigenous ones at a dosage that is sublethal to humans.
