A luta pela saúde dos oceanos

NOVA IORQUE – Os oceanos estão a mudar – e não é para melhor. Dados científicos bem definidos mostram que estão cada vez mais vazios, mais quentes e mais ácidos, colocando a vida marinha sob uma grande pressão. Mas há uma boa notícia: os dados também indicam que os oceanos podem regenerar e o mundo já concordou em permitir esse resultado.

O Objetivo de Desenvolvimento Sustentável para os Oceanos (SDG 14) foi aprovado pelos líderes mundiais, em setembro de 2015, como parte da Agenda 2030 para o Desenvolvimento Sustentável das Nações Unidas. Ele inclui objetivos fundamentais, tais como mitigar a acidificação dos oceanos, assegurar a proteção de habitats e de espécies, reduzir substancialmente a poluição, e acabar com a pesca ilegal e os subsídios que levam ao excesso de pesca.

    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.
