Yeah, it's a shame about all those little paradisical islands and tsunamis. I vaguely remember a documentary awhile back that looked at a bunch of islands and pointed out how most are periodically swept clean by big waves or winds or both, which is why so many are never populated very long (assuming they are large enough to have enough water and other resources to sustain even meager populations).
That made me recall a cruise to several Caribbean islands, comparatively large, seeing some inevitable trash here and there, and thinking how hurricanes and tsumanis are nature's vacuum cleaners, power washers, and leaf blowers, and most of the debris ends up somewhere in the briny deep.
If Earth ever drains dry, what a mess will emerge in every stream and ocean bed. Although even then, it's a big planet, and we might be more surprised to see how little we mattered after all.
