Governing the oceans
« The tragedy of the high seas », this is the title of an excellent paper published in The Economist on the 23rd February.
“Yet the state of the high seas is deteriorating. Arctic ice now melts away in summer. Dead zones are spreading. Two-thirds of the fish stocks in the high seas are over-exploited, even more than in the parts of the oceans under national control. And strange things are happening at a microbiological level.
The oceans produce half the planet’s supply of oxygen, mostly thanks to chlorophyll in aquatic algae. Concentrations of that chlorophyll are falling. That does not mean life will suffocate. But it could further damage the climate, since less oxygen means more carbon dioxide. (…)
… there should be more marine reserves. An eighth of the Earth’s land mass enjoys a measure of legal protection (such as national-park status). Less than 1% of the high seas does.”
