I'm so glad to hear that someone cares about the amount of plastic that we are dumping into the environment!
A few years back, I was in Greece at an ancient temple ruin (Temple of Hermoine) and the place was breathtakingly beautiful. The site was located on a coastal inlet and I was stunned at how many plastic particles had washed up on the beach. It was HORRIBLE. I hope we find a solution soon. More power to the caterpillars!
