Europeans were the ones traveling around between continents spreading plants from one to another without regard for the consequences.

Said no American ever. There are many things to have conflicts about between nationalities, especially now, but this is a weird one. Also, Europe is probably the continent with the most egregious history spreading invasive species.

Does this mean the Canadians like New England and the Northwest?

Honestly, I think China would take a bigger piece of the continental US.

Sounds like a you problem
