Humans have only been farming for the past 11,500ish years, while Homo sapiens have been around for more than 200,000 years. Humans modifying the environment to a significant extent is rather new in our timeline.

I don't know about that. There's at least speculation that some percentage of animals that went extinct in North America were due to humans. Also in North America there was a lot of impact to ground cover by people before agriculure - i.e. burning down forests to make it easier to hunt game. It's hard to imagine those things only occurred in the Americas.
