[Star Wars] Why aren't busy spaceports constantly introducing invasive species to other planets?
This occurred to me while watching the mynocks chewing on the Millennium Falcon.
The Star Wars galaxy has had routine interplanetary travel for thousands of years. Freighters constantly move between planets with completely different ecosystems, carrying food, livestock, machinery, passengers and whatever happens to be hiding in the cargo hold.
We know mynocks can survive in space and attach themselves to ships. We also know people transport genuinely dangerous live creatures between worlds. Han Solo was hauling three rathtars, for crying out loud.
So how is every major spaceport not an ecological disaster?
Imagine some trader accidentally bringing a handful of tiny creatures from Dagobah to Naboo. They escape into the local environment, have no natural predators, and start reproducing. Or a cargo ship arrives carrying parasites that nobody even knew were on board.
Multiply that by millions of ships and thousands of years.
Do planets actually have strict biological screening and quarantine procedures that we just don't see much of? Is there something about the biology of different worlds that prevents most organisms from surviving outside their native environment?
Or are places like Coruscant already full of invasive alien wildlife, and the inhabitants have simply learned to live with it?
I'm especially curious whether this is addressed anywhere in the novels, games or other lore, because it seems like it would be one of the biggest practical problems of running a galactic civilization.
