Tom Scott did a video a few years ago about New Zealand's attempt to eliminate rats by 2050.

The program is actually called "Predator Free 2050" and also aims to eliminate possums and stoats. No mention is made of Uruk-hai, orcs, or Balrogs.

>Uruk-hai, orcs, or Balrogs

Aren't they native?

Had they not been so greedy mining for mithril, maybe there wouldn't have been Balrogs. Not sure if that makes Balrogs invasive.

Aren't there only a few of them? Is a few invasive?

How does a balrog reproduce btw?

You see, when two Maia love each other very much...

Uruk-hai are GMO
