Death of the Oceans
Discussion
Was this (Death of the Oceans) watched by the PH masses last night? I caught a bit of it and from what I saw, it painted a pretty bleak picture of the over fishing of the Oceans.
It didn't strike me as the usual MMGW type of scaremongering either - Ehe size of some of those massive "trawlers" and the size of some nets is astounding.

To me, at any rate, it strikes me as a no brainer:
Trawlers are getting bigger and more technological and can find fish easier - the slow growing fish don't have a chance to recover and therefore don't grow so fast - fish dwindle and the trawlers go further and deeper to fish more.
I'm often surprised we have any fish left...

Was only half watching but sure there was some upside, was it in the US / Canada where some fish stocks were increasing.
Never struck me to think that the sea absorbed some of the CO2 which made it more acidic thus changing the whole eco system there.
Surely there needs to be some limits put in place on certain fishing otherwise the future does not look too good..

I tink the ecosystem is rather robust, it's just the amount of fishing we are doing is immense. As well as the other stuff.
Watched the doc The End of the Line a few weeks ago, was interesting.
It might have been in the same programme but I also recall seeing in a programme that Humboldt Squid is taking over in some parts of the ocean thanks to our destroying the eco system there.
Watch the doc, and see what you think of the Japanese response

Saw that quite scary, with the ex Navy Seal? Where they were basically attacking him in the ocean!Population growth. Needs to be curbed if we really want to "protect" these things. Root cause of many of life's ills.
Though I have a strong suspicion that the ecosystem at large is much more robust than it's being given credit. It will simply rid itself of its biggest parasite once it's had enough (whether it's the oceans, the ozone layer or just Big Brother and the XFactor)...us.

And, given the history of "Mother Nature", it'll be something pretty spectacular...wainy said:

Wow the sea is acidic ?I always thought it was alkaline so if anything made it less alkaline.
Still...calling the sea acidic gives it more doooooom value I suppose.

squid is quite tasty we should be tucking into these and leaving the fishees alone
Quite.Humboldt squid would produce calimari the size of 175 section car tyres
this would then restore some of the natural balance by taking two predators out of the eco system, us and squid
When I was navigating ships here there and everywhere it always struck me that you would only see fishing vessels in certain areas.
For example, on an ocean passage across the Indian Ocean you might see barely any fishing boats. Cross the East China Sea and it was fishing boats from horizon to horizon.
Certainly over fishing goes on, but only in certain areas I'd wager.
