Raising the temperature... Whose water is it anyway?

     A week or so ago I reported the good news that all we have to do is to eat organic and bring back the world to an organic system of food growing, as well reforesting, to not only stop global warming but reverse it.  This came in the form of an article and alert in  organic byte #227 from the Organic Consumers Association via a tweet.
     Never in the history  of mankind , surely, has such an important  piece of news been delivered in such a singular way!.... but there it is... you don't  need to do anything more fancy than going back to growing food the way our great grandparents did, to save the world.   
     This cannot come soon enough.  This week, I had a news update from The Ecologist, the ecological early warning  e magazine,  reporting on a paper by a Canadian researchers, headed by  Daniel Boyce, a PhD student at Dalhousie University, published in Nature.
     It appears that while the beneficial mycorrhizal fungi in the soil can seqester back all  the CO2 we produce and more, given half a chance;  the phytoplankton in the surface layers of the sea have not been doing so well.. In fact their numbers  have been going down worldwide each year by  1% since 1950. The Northern hemisphere has lost 40%.  This seems to be due to the temperature of the water going up.
     The Phytoplankton produce half the world's oxygen and remove carbon dioxide from the atmosphere, according to Boris Worm, another member of the team.
     You can find mention of it on the internet.. CBS has a short report, for one, which is where these figures came from, and which the link is to,  but there are others.
     It raises the question, do the billions and billions of gallons of water, sucked in by the nuclear power plants every day around the world, which also suck in and kill billions of small marine animals, have a crucial role in this?
    From some figures I obtained from Beyond Nuclear, by  going to  " Licensed to Kill"  (or go to 'Animals' and choose it from the drop down menu, or key it in their search box),  "Once Through" systems can raise the temperature of the water taken in by up to 25 degrees Fahrenheit when it is returned to the sea. These temperature changes and the huge volumes of water being returned to the surface layers of the seas makes me wonder if the very air we breath depends on their being closed down?  It may depend on no new ones being even considered..
 If these "once through" plants were all forced to close down until they had been retro fitted with cooling towers, it would reduce this problem..but before you think that's the answer, just look at the problems with cooling towers and tritium leaks and ask yourselves whether that is an especially good answer.
     In this country, Sellafield can take 4 million gallons of water a day from Wastwater,  a beauty spot in the Lake District, to keep the high level liquid wastes from boiling,  that's a lot in a year, but unlike the nuclear power plants, you can't shut down the cooling to the tanks, because the radioactivity in them causes the liquids to get hotter and hotter, and the wastes have to be kept cool for years and years.  Meanwhile, local people are complaining about a hosepipe ban!
     There are alternatives and you are entitled to a secure future... all of you.  But don't worry about global warming, you can still munch your way out of it.  Will there be enough for everyone... well, if you read "Don't Panic, Go Organic", also in the OCA., of course there will.
