In case anyone thinks Andy's scenario is completely off the wall:

What he's describing is already happening. Maybe not on your patch, maybe not on mine, maybe not right now. But if you want to look at the sea today and extrapolate a possible future if things continue as they are, it's as good a description as any. It's not meant to be alarmist, an exaggeration or anything except an attempt to provoke some thought by anyone who hasn't happened to think along these lines yet.
You all remember last year's 'red tide' and what fun that was. We could soon have that one in spades, all year round. Global warming and increasing pollution loads in the sea are all that is required. Imagine a sea that was giving off a toxic mist from all the algae that would affect you mile or so inland. Forget fishing, boating, trips to the seaside.
A few people might be surprised that there really is a market and a commercial fishery for jellyfish. More profitable than chasing the remaining fish and shellfish. How do we suppose that came about?
Ask yourself to project a bit further into our future. Since we have pretty much wiped out the jellyfish's natural predators and are creating ideal conditions for their population to explode with all the nitrate/phosphate/sulphate pollution, mostly from intensive agriculture, if we fish out the jellyfish, what'll benefit from that? Algae. Some of which are downright nasty to man, fish and beast alike.
So do we want to sit idly by while other people destroy the seas?
Some of us don't, but then again, we don't want to have to spend our time working on conservation issues, angling politics and the like. We would much rather be fishing, and would love to be catching. But somebody has to do it...
