Love this idea. So obvious yet so fresh. I think it's because we live on autopilot most of the time. We passively accept the things we use as "the way it just is". Or that it's not up to us, or not our responsibility.

Case in point is litter in scenic areas (or anywhere). People just ignore it, even when it's completely in front of them. It's like a negative hallucination. When people do see it, it's not their responsibility and dismiss it. It's so ingrained its almost instant.

The environment, the water is OUR responsibility. Don't leave it for someone else to deal with.
