Tuna and mackerel populations suffer catastrophic 74% decline, research shows

WWF and the Zoological Society of London found that numbers of the scombridae family of fish, which also includes bonito, fell by 74% between 1970 and 2012, outstripping a decline of 49% for 1,234 ocean species over the same period. 

The conservation charity warned that we face losing species critical to human food security, unless drastic action is taken to halt overfishing and other threats to marine life.

Louise Heaps, chief advisor on marine policy at WWF UK, said:

Agelbert NOTE: The typical reaction (by the fossil fuelers and N.T.H.E. threat denying wishful thinkers) to the above will be the wailing and gnashing of teeth about "overpopulation"  . However, Global Warming caused CO2 ocean acidification and other industrial and big ag pollutants like chemical fertilizers will be, uh, mentioned in passing, THUS: "we are solving all that with incremental measures. No need to get so excited. We must weigh the benefits to society of business as usual against the "minor" cost of collapsing tuna, mackerel, shellfish, sea cucumbers, sea turtles, etc., populations. There is no reason to let this alarmist news stampede us in to any rash activity that might threaten GDP!". 

Right after that they will scream for all those "useless eaters" out there to stop driving tuna sandwich prices up! The "job creator" one percent wants to serve champagne and caviar, not tuna casserole! 

Palloy tries to downplay the above marine species extinction threat. Palloy does not get it. I will explain why.

At the risk of being called a shill for the fossil fuel industry by AG, again, I should just like to point out that the pH of the oceans varies between 8.1 and 8.4, and that so far climate change hasn't altered that by 0.1 anywhere at all.  It would happen in time of course, IF we continued to burn fossil fuels at the same, or increasing rates.  But if you believe in Peak Fossils then that won't happen - not because THEY wouldn't want to, but because they won't be able to make money out of it.  That's when they will stop extracting fossil fuels, and industrial civilisation will collapse.

Temperatures will continue to rise maybe until 2045, and ocean acidification will continue, but industrialised fishing will be over almost instantly, and fish stocks will replenish quickly.  The mix of species will be different, no doubt, but they have always been different, and nobody is really aware of what the mix is anyway.

So don't worry, just pray the collapse happens soon.

Sigh, you mathematicians don't do much biosphere math, do you? What YOU call "insignificant" pH (you know, the negative logarithm of the hydrogen ion concentration) differences have VERY significant (as in homeostatic band required) effects on living systems (you know, the stuff we eat!).

Homeostasis REQUIRES that strict pH (and temperature and pressure and dissolved CO2 and dissolved O2, etc.) bands be adhered to or the organism dies. The reason it dies is because thousands to millions of biochemical reactions per second, vital to living processes, will not take place outside those homeostatic bands.

For mathematicians, the numbers are "significant" if they are, say, 2% or more and INSIGNIFICANT when they vary less than that.

For biologists, the numbers are homeostatic band life or death SIGNIFICANT when they vary by 0.01 % - often even less!).

This is so because the enzymes (catalysts made by living systems to lower the energy of activation for chemical reactions so the organism does not overheat and die from chemical reaction waste heat inefficiencies) will NOT take place when the pH (in combination with the other factors I mentioned) varies by a very small percentage. And all these bands vary in different parts of the human body. The pH band your bloodstream can handle is far less than the one the water in your tissues can handle.

There is a LOT MORE to this.

For example, I'm sure you would agree that being drunk is hazardous to your health because it slows your reflexes, dehydrates you, stresses your kidneys and liver and blinds you to reality because the system thinks it is pigging out on cheap energy - sends your brain a signal that everything is amazingly great (that's called being high).

The change in concentration of alcohol in the blood required to effect all these deleterious changes (that the organism itself perceives INCORRECTLY  as  "good" because it FEELS good") is, from your point of view, tiny.

Biosphere math is DIFFERENT from the math applied to non-living matter, Palloy. Stop trying to apply your math to living systems. It is tantamount to peddling rose colored glasses about the severity of our environmental plight.   

Here's one more example of how a pollutant in our atmosphere that kills life is actually made by living systems to preserve life. It's all in the percentages, Palloy. It's all in where the polluting gas is and how much of it there is. The life or death differences in percentage are FAR LESS than 0.01%.

The gas I refer to is Nitric Oxide (NO).

Environmental effects

Nitric oxide in the air may convert to nitric acid, which has been implicated in acid rain. However, it is an important source of nutrition for plant life in the form of nitrates. Furthermore, both NO and NO2 participate in ozone layer depletion.

https://en.wikipedia.org/wiki/Nitric_oxide


Humans make Nitric oxide in their noses to kill bacteria before it gets to their lungs. This is why breathing through your nose is a good idea.  ;D

But the percentage is so tiny that a fellow like you would claim it was "insignificant" if it was no longer there (which would guarantee bacterial attacks on the lung tissue  :P).

On the other hand, if we breath too much  Nitric oxide because it's in the atmosphere as a pollutant, it can destroy tissue. And before it does that, it will vasodilate the begeezes out of your blood vessels, depleting your ability to get oxygen to your brain and everywhere else in your body. Too much, by a very small percentage, will kill you.

This is what homeostasis is ALL ABOUT. This is why Lovelock used the homeostatic analogy in his Gaia hypothesis. He understood the incredibly small percentage of variation that our biosphere REQUIRES to be viable. The fact that most people are not aware of this is used by the deluded wishful thinkers to claim the gravity of our situation can be solved by killing off most of the human population. NEVER MIND that the top 20% will still be there doing 80% of the damage.


The collapse of the human population will not allow the fish populations to rebound simply because EATING the fish, though a contributing factor, is not the main reason they are headed for extinction.

Your post is biosphere reality challenged. It's time for you to take of the "culling the population will solve all our problems" rose colored glasses.

How can Palloy be right about percentages and WRONG about the deleterious impact on marine species at the same time?  :icon_scratch:  First of all, he refused to state the TREND when he said that  "pH of the oceans varies between 8.1 and 8.4". This is double talk for, "it's no big deal". To cover his illogical ass he then says that "eventually" it's gonna happen. LOL! A brain dead person knows that! His entire post lowballs the  existential threat for marine species due to CO2 caused ocean acidification. This is what irresponsible defenders of the polluting energy status quo DO.

OA Observations and Data

Follow the links below to access ocean acidification data for each of our observation programs

The field of carbon cycle science depends on well-designed, well-executed, and carefully maintained observations.  The PMEL carbon group primarily focuses on large scale observations of ocean interior carbon through hydrographic cruises and surface ocean carbon dynamics through measurements made on volunteer observing ships, buoys, and other autonomous systems. We work in both the open ocean and in coastal environments. We maintain long-term time series observations as well as conducting short term process studies or exploratory studies.  Since ocean acidification emerged as an important scientific issue, we have been augmenting and expanding our observational capacity by adding pH and other biogeochemical measurements to the platforms listed below.
