RE: The Holocene Mass Extinction Part 2: Nonstop Invasions
Thanks for reading! And yeah, bilges are the primary method of transport for marine invasive species these days- we need to pass international laws requiring freshwater bilges to be dumped in saltwater and vice versa to kill hitchhiking invasive species.
Would the amount of swapped water cause any sort of disruption in the area of the dump for the micro-systems living close? Still a better trade off I would suppose. Would be cool if we could build a "dump tank" -like area where we could trap marine life out. That way they aren't shocked by the dump either. Just the transient alien life forms, lol. Great topic of discussion you have going here.
Thanks! And yeah, I'm sure there'd be issues- it's a stopgap measure at best. Actual ballast tank purification systems would be expensive and difficult to enforce, but it does need to happen eventually.
