Yes, there's a lot of research on containment and the ability to corral species to direct them to areas where we could fish them out. We could poison a smaller area. There's a ton of research under way to have a plan B. The idea is that the game is not over and we would be able to slow or prevent the spread and subsequent consequences. Delaying that process buys us more time for further research and the ability to fish them out and move them into an area where we can eradicate them.
