I think that boaters, divers and others who are able to spend time on or in the water are lucky for many reasons, but especially because we have the opportunity to see nature very close up, very vividly.
For the most part, this vividness is a good thing. You can see and experience a variety of interesting and beautiful things – sea life, shore birds and marine mammals, to name a few. The downside is that you may also have a close-up view to pollution, debris, death and decay. And, unfortunately, sometimes these two are inseparable, intertwined.
