Piscicultura asesina

Según las conclusiones de un informe reciente de la Organización de las Naciones Unidas para la Agricultura y la Alimentación, casi la mitad de todo el pescado que se consume en todo el mundo está criado en granjas piscícolas y no capturado en su medio natural. Es probable que ningún consumo de pescado haya aumentado tan vertiginosamente como el del salmón procedente de granjas piscícolas, pues su producción se ha incrementado en casi un 300 por ciento en veinte años.

Sin embargo, el salmón es carnívoro y, para alimentar el voraz apetito de esas legiones de pescado criado en granjas piscícolas, la industria de la piscicultura ha ido prestando atención cada vez más a un pequeño crustáceo comúnmente conocido como krill antártico, pero ésa es una mala noticia para las focas leopardo, los pingüinos de Adelia, las ballenas jorobadas y las ballenas azules y muchas otras especies, porque la mayoría de los microorganismos del ecosistema marino antártico comen krill u otras especies que comen krill.

El krill, que se encuentra en las aguas frías del océano Austral, constituye un ingrediente principal del aceite y la harina de pescado. Lamentablemente, investigaciones recientes indican que el aumento de la pesca de krill podría poner en peligro el ecosistema antártico. Los representantes de las más importantes naciones pescadoras del mundo, que se reunirán este otoño en Australia, tienen la oportunidad de limitar las capturas de krill, con lo que ayudarían a las especies que necesitan el krill para sobrevivir.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
