It is a fallacy to say scientists don't know what is causing it but they/we know its humans for sure! Huh? What?! That don't make no damn sense. You got to know

It is a fallacy to say scientists don't know what is causing it but they/we know its humans for sure! Huh? What?! That don't make no damn sense. You got to know something before you know it, you know? In your vulture example we know why the vultures died so we can tie it to a human behavior. We don't know why the bees die or what the deal is with the mites so we can't tie it to human behavior. You are still making a leap of faith, no matter how logical or likely it seems or in fact is.
