oxygen production. plankton are the foundation of the ocean ecosystem. i'm a lefty, but this seems like a win win. change will happen. but no more than when we make hydroelectric dams that drastically change the water temperature so all of the indigenous fish die and have to be replaced with colder water species. and these types of changes are justified every day. I really don't see a problem with this. let's do a study to see what happens when we offer fish more food. you get more fish.
