First Sierra Leone, now France- beaches blanketed by toxic seaweed

July 28, 2011FRANCE – Toxic blue-green algae has killed 31 wild boar in a cove in Brittany, northern France. The algae is common on beaches in the area but turns deadly when it comes into contact with nitrogen waste flowing to the cove from intensive pig farms near the Gouessant estuary. The gas is as toxic as cyanide, prompting local authorities to close nearby beaches. In 2009 fumes from the seaweed-like sludge knocked out a council worker clearing the beach. A local horse rider also passed out and their horse died. –9 News

    This problem isn’t from yesterday…
    It starten in the 70’s.
    I remember when I was a child and going in hollidays to Brittany.
    I remember these green beaches and the horrible smell of these algae.
    Our government is acting on the wrong manner, removing the algae from the beaches, but nothing is done to fight the real cause of the problem : the intense release of nitrates by our agriculture.

    This is especially saddening to me because I use Celtic sea salt which is farmed in Brittany. Have been using it for several years and I am not dead. It contains about 87 minerals as opposed to common salt which is basically poison, other than using it to bathe wounds etc.

    I have a fair supply on hand as I often have thought what if there is a problem of some sort in the sea over there.

    Just another reason for being prepared and having some extra supplies stored.


  4. actually the problem is not just in france, its also very huge in china, and now folks – coming to the uk.
    Sure, blame it on Pig farming – or runoffs from agriculture – but the real reason is something a bit more sinister – in the 70s a major industry started taking off – here in Norway it is still in full swing and that is why the problem is only going to get worse – seaweed harvesting.
    Seaweed is like the rain forest, its the lungs and liver of the sea – it removes nitrogen and phosphates and more. Brazil lost theirs entirely – in the uk theyre a bit more beaurocratic so its limited, but here in Norway its in full swing – 200,000 tons per year.
    All the seas are linked, so what heppens here is happening to you – ahh, france takes out about 70,000 tons – the same as it has to remove from the beaches per year.
    As long as the target is something other than seaweed harvesting everybody is happy – even though its killing the sea – this is not rocket science – you can see the same happening in a pond.
    if the pond has higher plants – the water is clear, if none it soon turns to a cloudy soup –
    I think the case in Sierra Leone may be a little different.
    So what do we have to look forward to – vast algal blooms, red tides and more –
    All because these companies make money from seaweed.

    This is from Netalgae (the eu organization responsible for promoting seaweed removal (harvesting)) a report on the european seaweed industry – the french industry. The Norwegian industry

    Click to access Norwegian_seaweed_industry_WP12.pdf

    The figures for Nitrogen removal for the Norwegian seaweed is 480 tons per 20 square kilometers . The entire Norwegian coast where it is possible to harvest is being exploited(as you can see from the document) – our seabirds are dying – The seaweed concerned on the French coast – Ulva is well known to take over from other seaweed specis when they have been removed.
    Pig farming is strictly regulated – it is relatively easy to source the materials responsible for this algal explosion – i wonder what testing has been done
