At this point whenever I'm on a walk I clean up any plastic litter I spot and dispose of it. I live not too far from some creeks and retention ponds along a local flood plain where I know my neighborhood's storm drains are headed. Seeing so much plastic litter and other pollutants spoil a habitat that once supported a very vibrant ecosystem was sad to watch, and I'm doing whatever small things I can to help. But we need systemic change to deal with plastic pollution.

(The fish died from lawn runoff causing algae blooms as well - please be aware that if you live somewhere where it rains, then over fertilizing pollutes.)
