Let's hope it works! I have some experience with attempting to collect trash from polluted waterways using booms and I can tell you it is difficult to collect only trash. I'm guessing lots of living things that are growing on or living around this trash will be collected (and killed). Probably still a net plus for the environment, but hard to do perfectly. With all the places banning plastic bags and straws and the new developments in plastic degrading enzymes and organisms, I have hope we will be able to make great progress tackling the plastic pollution problem in the coming years.
