No. I'd be shocked if an apple tree started growing in a forest because someone chucked a core back there. Apple trees... kinda suck, they aren't very robust and they grow best in full sun. With that said I do agree in principle that people should be more careful with invasive plants I just dont see apples outcompeting actual forest trees in a forest. Also they can't self pollinate so that tree wouldn't be able to produce fruit and future apple trees anyways.

It's a "dad joke" for the entire animal kingdom. Shitting out the seeds is quite literally how plants survive and flourish through the ages (before Monsanto genetically nerfed em anyway).

oops, replied at the wrong level... I was referring to the "shit habit"
