I just came from a supermarket. I was looking at all the seafood that was available. Not just the fresh catches, but also the frozen food. Large containers full of prawns of all sizes. Containers full of shell fish. Containers full of parts of other sea animals. I found it really quite something to behold. What a rich variety of species live in our oceans.

I was looking at this display in a fairly average sized supermarket in a small town. My mind then started extrapolating that quantity of sea food in food stores across the world. How does the natural world keep up with that kind of demand? I guess that current environmental measurements suggest that it isn’t, or at best is struggling.
