They probably transform the planet more than almost any other critter besides beavers (which dam up a lot of rivers to create ponds and lakes).

I think you are right!
In South America they imported beavers from Canada. Today, this is a real problem for them.
That is interesting... unforeseen consequences huh?!
Speaking of beavers, this one in Maryland ran into a dollar store and didn't like the fake Christmas trees. https://www.washingtonpost.com/news/local/wp/2016/12/01/cute-beaver-trashes-store-after-holiday-shopping-in-maryland/?utm_term=.3dbbab48e173
That is hilarious! It almost looked like it was planted there for pictures! Can you imagine shopping there and running into that as you turn the aisle? :)
Yes, the non-native species can be a problem in a lot of countries. Ecosystems take a long time to evolve and include them in the balance of life.
