La pisciculture est meurtrière

Selon un récent rapport de l’Organisation des Nations Unies pour l’alimentation et l’agriculture, près de la moitié des poissons consommés dans le monde ne sont pas pêchés dans leur milieu naturel, mais proviennent d’exploitations piscicoles. La consommation du saumon d’élevage bat des records, avec une production qui a augmenté de 300 % en 20 ans.

Les saumons étant carnivores, l’industrie de l’aquaculture s’est tournée progressivement vers un petit crustacé connu sous le nom de « krill antarctique », pour nourrir les appétits voraces de ces légions de poissons d’élevage. C’est une mauvaise nouvelle pour les léopards des mers, les pingouins d’Adélie, les baleines à bosse, les baleines bleues et pour les nombreuses autres espèces de l’écosystème marin de l’Antarctique qui se nourrissent soit de krill, soit d’un animal qui se nourrit de krill.

Présent dans les eaux froides de l’océan Austral, le krill est l’un des éléments essentiels de l’huile de poisson et de l’alimentation animale. Il ressort malheureusement des dernières recherches que l’essor de la pêche du krill pourrait nuire à l’écosystème antarctique. Les représentants des grandes nations de pêche se rencontrent à l’automne en Australie : ils ont la possibilité de limiter les zones de pêche, pour venir au secours des créatures qui ont besoin du krill pour survivre.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
