Critical Reasoning (CR) | Re: All oceangoing ships carry seawater ballast tanks whose weigh

Imagine that your ship unloads some cargo at a port, refills the tanks before leaving port, and in the process accidentally picks up some Seussian Dogfish, a (made-up) coastal sea creature.

Once the ship reaches the middle of the ocean, the tanks are emptied, releasing the Seussian Dogfish. According to the argument, the Seussian Dogfish will probably die (since coastal sea creatures usually cannot survive in a midocean habitat) and thus probably won't wreak ecological havoc.

But what if, going against the proposed solution, we dump some Seussian Dogfish at a DIFFERENT port thousands of miles away?

That would be a NEW habitat for the Seussian Dogfish. Since it's a COASTAL habitat, we don't have any reason to believe that the Seussian Dogfish will die. So the Seussian Dogfish might wreak ecological havoc in the new coastal habitat.
