Though one wonders why one would do that instead of simply doing

print var

I googled the walleye. They seem to be quite the capable fish. They look fast, with a great set of choppers and what a set of fins!

That sounds like something the Swedes would eat. :-)

Good point. On the other hand, Patagonian toothfish have a lot of good points.

Ain't no doubt about it - that Patagonian toothfish is one bad
motherf***shut yo mouth!

The transformation of this nasty, evil, devilfish to the docile, happy,
sea bass could be used on humans with a high spousal disparity
coefficient. If your coefficient is approaching 1 - i.e., you're a crazy
old geezer that thinks he's Jesus, you need this treatment! As far as I
know, this involves getting skewered through the gut with a speargun and
being dragged behind the wake of a large fishing vessel.

Yeah, it's been some time that I've been hearing about the severe overfishing and fortunately, since I know in the cases I've asked where they said they knew about the overfishing, I don't see it being served much for a while.

Not just fish but the whole ocean and riparian areas are getting clobbered by us. Sadly invasive critters and plants are really off the radar while we run around looking for someone to blame.

Recently a leader of one island nation suggested their military blow the poachers out of the water, and I know people who honestly believe their government should let the people shoot "illegals" who are the ones they blame for over fishing.

There is a lot of work in education and there are limits to what we can do without understanding how connected we are. The recent Red Lobster deal will have a direct impact on people I know and the ecology of their island nation.

Our choices matter but it's all cost shifted so we can't see how messed up it is. The old islanders talk about lobster covering the beaches so you could just pick up a bucket and have a great meal, and there are pictures of them doing that in the 60s. In my lifetime our exponential growth and increasing mobility have made our globe into a giant trash pit. We are pathetic and the future will not be kind to us.
