This looks like a really great beginning! I was interested in this jam topic because this was something that came to my mind the last time I visited Hawaii. There was so much degradation from all the tourists. We did our little part: picking up trash, only travelling around the island by bus, and visiting several sites dedicated to projects attempting to restore the ecosystem and culture of the island.
I think your project really has the potential to get people thinking about their impact and how to counteract that impact.
