Who don't like fish sticks?

It's okay, Jesus will put more fish there, and maybe some loaves too.

If flat floors werent all around better for inhabitants, then why do concrete finishers have jobs? These guys should be charging extra for actually smoothing out the seafloor.

Can we prove this causes bigger Tsunamis, by reducing the friction loss of the waves as they get nearer to shore?

To be fair, in the politics tab, it's kind of hard to tell the bottom trawlers from the genuinely-believe-their-own-derp folks.

Saw this and called my brother for info. He did a long stint with the NMFS as an observer/onboard cop to make sure the fishermen and crabbers were following the law. The major problem with the bottom trawlers and scallop dredges, aside from smoothing out the bottom and stirring up huge amounts of sediment, is the fact that about 95%-99%- of what they catch is by-catch; thrown back overboard and not harvested. This means huge amounts of crab, shellfish, eels etc are just destroyed.

There is a lot of sentiment around banning such methods as the long drift nets were back in the mid 90s. While economically efficient, they do far too much damage to the seafloor to keep the fisheries viable. Often, areas that were harvest out over a period of a few years are not usable for a decade or more afterwards. The Japanese use this method to harvest Krill directly, the bottom of the food chain.

We're effectively sterilizing the oceans. The biggest mass extinction since the end of the Pleistocene, and it is entirely human-caused.

Lol. It's the height of arrogance to think that we could "kill" the planet. Earth is billions of years old and has had much worse than man unleashed upon it. It's still spinning. It'll still be spinning, with life crawling all up in it, long after we're gone.

Your right, we almost certainly won't be able to destroy all life on the planet. That won't happen until the sun expands and swallows up the planet. Rendering it inhabitable for human life is much easier; and were doing a bang up job of working towards that happening.

Meh, Americans don't eat as much seafood per capita compared to Europeans and Asians.

If fisheries do collapse, they'll feel more pain, so I'm okay with that.
 
2012-09-07 12:09:49 PM  
Many commercial fishermen/corporations don't give a shiat about it and will willingly maul the fishery into extinction.

/[citiation needed]? Just study history.

If you only knew how destructive some fishing practices were, you would descend on congress with pitchforks and torches demanding change.

Yep - but what puzzles me is why we humans think we so frigging important. I mean, in the grand scheme of things the planet and universe could give a crap about this tiny blip of human existence. We WILL become extinct, we are not the most important thing. I'm not suggesting we all give up and just kill each other off, but I'm saying we need to keep things in perspective. We are just another flawed life form that will fail sooner or later. I get the sense that some people think we can save the species for all of time.

I've always wondered how much ancient and even recent historical items and sites are destroyed every year by doing this. The Antikythera mechanism would have been smashed by this process if it was in the path of a trawler. then again a trawler discovered the wreck of Antoine de Saint-Exupéry P-38.

The Total Perspective Vortex derives its picture of the whole Universe on the principle of extrapolated matter analyses. To explain --- since every piece of matter in the Universe is in some way affected by every other piece of matter in the Universe, it is in theory possible to extrapolate the whole of creation (every sun, every planet, their orbits, their composition and their economic and social history) from, say, one small piece of fairy cake.

The man who invented the Total Perspective Vortex did so basically in order to annoy his wife.

Trin Tragula (for that was his name) was a dreamer, a thinker, a speculative philosopher or, as his wife would have it, an idiot. And she would nag him incessantly about the utterly inordinate amount of time he spent staring out into space, or mulling over the mechanics of safety pins, or doing spectrographic analyses of pieces of fairy cake.

"Have some sense of proportion!" she would say, sometimes as often as thirty-eight times in a single day.

And so he built the Total Perspective Vortex --- just to show her. And into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she saw in one instant the whole infinity of creation and herself in relation to it. To Trin Tragula's horror, the shock completely annihilated her brain; but to his satisfaction he realized that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it cannot afford to have is a sense of proportion.

How can I help? Perhaps have the government mandate some sort of 'smooth-ocean-floor offset" tax. Like carbon credits, except for the ocean. Because it is everyones responsibility!

It's a side effect of our capacity for cognition (and thus ability to create technology. It's made us the dominant species on the planet, but also the most destructive one.

They key is that we can also choose not to be so destructive.

This is one of those "doesn't need further study because it is that blindly obvious" things, like what happens when you dump really bad, long lasting chemicals into the water supply because your cheap, lazy ass doesn't want to pay for proper disposal.

Kids, we can bat "global warming" as a problem around like a beach ball for hours and no one is going to change their mind. This...much different.

The only way to destroy the Earth, and all life on it, would be to fling it into the Sun. There is life on every ccm of this planet, as far down as we can dig, everywhere we look.

All things strive. All the billions of extinct species didn't just lay down and die (some of them fell over). Er. Let me start again.

The most successful species are the ones that did not go gently into that good night, but fought against the inevitable and adapted. That statement is so anthropomorphised as to be factually incorrect, but you get the idea. Giving up is a poor evolutionary strategy.

They don't even know if this is good or bad... it could hurt other species, while allowing others to thrive... that's how evolution and an ecosystem work. All organism interplaying and interacting and affecting each other. Dunno why humans want to exlude themselves from nature. Sure, we alter our environment on a megalithic scale, but on a fundamental level, we're just interacting with our environment like any other species on the planet, and other species around them are affected by it.

This could be destructive, it could beneficial, or it could be neutral. We'll have to wait and see...
