You cite -one- book that maybe says what you want to think and looks more opinion than science. You write also a quote about politics and there is also that old feeling of "we humans are the worst" in the air that can feel justified but never solved anything.

I have a PhD in biology and frankly I'm sick of discussing this issue each time again and again.

Are you solely focused on plants here? Invasive species can also apply to animals. Invasive aquatic species have decimate local animals, and we didn't necessarily create those environments. There's also invasive plants in these aquatic systems as well.

Yes thank you for this clarification. Apologies for my being imprecise. Most of the reading I have done has been related to plants and the use of pesticides to intervene.

Burmese pythons in Florida is another example of a pristine environment full of predators invaded (and modified) with no effort.
