Actual answer: Mr Trash Wheel runs so slowly that fish, ducks and crabs can move out of the way.
This doesn’t prevent stuff like plankton from being “cleaned” too, and I feel that would cause ecosystem issues
Ending the behavior doesn’t clean up the problem.
Developing technologies means mitigating negative externalities. You don’t just design a pressure cooker and ignore the possibility it might explode because you “can’t force people to not leave it unattended”, you spend the extra time and money to design and install a safety valve.
Can’t fish just swim out? I don’t think there’s a net under the water.
There is a net, but it’s shallow, allowing the fish to swim underneath, while trapping most plastics, which generally float.
They can, it’s harmless to the wildlife.
¿Por qué no los dos?
Make the polluters pay fines/taxes and use the money to improve the cleaning robot
AI is sounding more and more like Maxwell’s Demon
