Le défi de la biodiversité

LONDRES – Si l’on en juge par l’ONU qui a déclaré cette année Année Internationale de la biodiversité et par la Convention sur la biodiversité qui se tient au Japon, il est clair que les défis environnementaux auxquels nous sommes confrontés sont graves et croissants, et qu’il est plus que jamais urgent d’agir.

Nos vies, comme celles des autres créatures de notre planète, font partie et dépendent de la biodiversité. En termes simples, la biodiversité est le tissu de notre existence, impliquant tous les organismes trouvés dans les différents habitats, des poissons des eaux profondes aux oiseaux des forêts tropicales, et tout ce qui se trouve entre les deux.

Les plantes et la diversité fongique sont les propres fondations de la biodiversité dont dépendent toutes les autres formes de vie. Les plantes absorbent le dioxyde de carbone et produisent de l’oxygène, nous fournissant ainsi l’air que nous respirons et contribuant à réguler le climat. Elles fournissent de la nourriture, des médicaments, de l’énergie, des abris, de l’eau potable et des sols fertiles. C’est grâce à la diversité des plantes que nous nous maintenons et, à l’avenir, c’est elle qui nous permettra de nous adapter, d’innover et en fin de compte, de survivre.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
