If they get out of hand, just bring in another species that preys on the spiders, problem solved :)

That's the beauty of it. When winter rolls around, the gorillas simply freeze to death.

For those that didn't watch the Simpsons, this is very relevant: https://www.youtube.com/watch?v=LuiK7jcC1fY

Just like the salmon brought into the Great Lakes to take on the alewives. Which were brought in to take on the zebra muscles[0]. Which came in [bilges from ships?].

I remember visiting the Lake Michigan dunes in Indiana in the 70s, only to encounter what appeared to the small me to be mountains of dead alewife. Ten years later, my grandfather took me salmon fishing there. I'd imagine that by now, the ecosystems of the Great Lakes bear little resemblance to what they contained 200 years ago. Sad in a way, but the whole of Earth seems destined to becoming a single, climate-based ecosystem. Island ecologies may survive for a few centuries, but the main continents are going to become very consistent, with all the world-champion species holding sway.

Do you need any rabbits? Cheers from Australia

Can human be considered an invasive species? Everywhere humans go, ecosystem disruption will soon follow.
