"What could go wrong". So what happens when these trees start spreading to other forests, growing there and pushing out all other native species and thus destroying original forests? Even if they'd make them "incapable of pollinating" the trees would eventualy still be able to pollinate since they'd eventual just mutate back: you have NO way of preventing that. It would be the same story as those GMO mosquitoes where scientists guaranteed us they could not breed. Until they could lmao. This is ignorant science, are these people even capable of thinking of even 2nd order effects?
