  • Global warming and the loss of biodiversity are closely interlinked — in both ways

    Screenshot from the video mentioned

    Human civilisation has exploited the planet to such an extent that life is under threat — including our own survival. There is still a way out of this catastrophe if we recognise what has gone wrong and act accordingly.

    Humanity uses 1.3 billion acres for intensive agriculture, whilst 2 billion hectares have already been abandoned due to overuse and depletion. The planet’s plant biomass has decreased by 50%. To date, 73% of all species are in decline. 10,000 years ago, 95% of animal biomass consisted of wild animals, whereas today 95% of animal biomass consists of humans and their domesticated species, i.e. mainly farm animals. The biomass of marine fish has decreased by 60 to 80%, mainly over the last 100 years. The planet has lost around 50% of its productive capacity.

    However, if we let cover large parts of land with trees and shrubs, we could significantly boost photosynthesis, create more life, reduce water consumption for plant care, and gain more shade, greater biodiversity, and a landscape that protects us from the extremes to which we are exposed as a result of man-made global warming.

  • Whale news

    As we’ve been talking a lot about one particular whale recently, here’s some news about lots of other whales.

  • Eric, der strenge Fischereiaufseher

    Heute vor sechs Jahren hab ich die Texte zu meinem Buch über die Geschichte von fair-fish abgeliefert [1]

    Vor etwa zwanzig Jahren entstand diese Foto während eines Gesprächs mit Eric, dem damaligen Chef du Service de Pêche du Département Foudiougne, dem strengsten Fischereiaufseher, dem ich im Senegal jemals begegnet war.

  • How to block bottom trawling

    Dragging huge nets on heavy runners or rollers across the seadbed is the second most destructive fishing method after dynamite fishing. For years, many organisations have been calling for a ban on bottom trawling, so far to no avail. Local communities face the challenge of defending their fishing grounds on their own. Concrete blocks and art sculptures are their weapons.

  • When legs lost at sea live on

    There are animals that can regrow lost limbs, such as the famous lizard’s tail. However, their old tail simply dies off and rots away. Not so the tiny feet and tentacles of the Scarlet sea cucumber (Psolus fabricii), a strange animal that lives on the rocks in the cold regions of the Atlantic and Arctic Oceans — not only can it regrow limbs lost to predators, but lost feet and tentacles are capable of surviving independently for more than three years, as recent research has shown.

  • Artisanal fishermen make decisions that many leaders would be incapable of making

    With thanks for these thoughts to Gaoussou Gueye and  CAOPA
    Traduit du français ; voir ci-dessous pour le texte original


    In Africa, artisanal fishermen make such decisions every single day. Because at sea, misjudging the risks doesn’t just cost a quarter’s profits.

  • The paradox in animal welfare

    According to representative surveys, almost all consumers disapprove of the way farm animals are kept. However, the market is not responding to this sentiment: supermarkets continue to sell meat from animals that have suffered – and consumers continue to eat large quantities of meat, and fish as well.

  • Was ist ein Wal wert?

    Es stimmt nachdenklich, wie Menschen eines ganzen Landes und weit darüber hinaus seit Tagen um 1 (in Worten: einen) Wal bangen. Wie sie sich dabei gegenseitig in Aufregung darüber versetzen: dass die einen angeblich wüssten, wie dem in die Ostsee verirrten «Willy» zu helfen wäre, und die anderen nichts unternähmen. Und nichts wird besser, während die Menschheit jeden Tag einen Schritt weiter Richtung Abgrund schlurft.

  • Fishing restrictions and science


    Governments are often criticised for failing to follow scientific advice when setting overly generous fishing quotas. But what if authorities, driven by political campaigns, disregard scientific findings — in the opposite direction?
