 And we know that. So we know that there are species that if you heat them up to the temperatures that would kill kitscher, they will die because that's just not a temperature they would ever experience or be adapted to. So the frogs themselves couldn't tolerate the temperatures needed. And different ecologies. There are frogs that live underground for months and years at a time. This isn't really a strategy that would work for them. And so you kind of have to take this biodiversity approach where you have to treat each frog as unique.
