La riqueza de especies

Aunque existe un amplio consenso entre la comunidad científica en el sentido de que la pérdida de diversidad biológica es una de las más serias amenazas ambientales, el público no está tan conciente de la magnitud del peligro. Los ecólogos y otros científicos del medio ambiente tienen parte de la culpa por no haber logrado hacer que sus preocupaciones sean importantes para la gente común. Pero quienes hacen más difícil su reto son aquéllos que afirman que los temores sobre la reducción de la biodiversidad son una conspiración de los fanáticos del ambiente para poner a la naturaleza por encima de la gente.

Nada podría estar más alejado de la verdad. Las amenazas a la biodiversidad pueden significar la pérdida de elementos clave de los sistemas de soporte de la vida humana, y por lo tanto ponen en peligro nuestro bienestar personal y económico. Ya no se pueden retrasar las medidas correctivas.

Quienes sostienen que la crisis de la biodiversidad es inventada, o que al menos está inflada, suelen señalar las estimaciones a veces exageradas que aparecen en la prensa sobre los ritmos de extinción. Los críticos aprovechan esas exageraciones para decir que en realidad el problema no es tan grave.

  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.
