Plastic planet

Image copyrightGetty Images Marine life is facing “irreparable damage” from the millions of tonnes of plastic waste which ends up in the oceans each year, the United Nations has warned. “This is a planetary crisis… we are ruining the ecosystem of the ocean,” UN oceans chief Lisa Svensson told the BBC this week. But how does this happen, where is most at risk and what damage does this plastic actually do? Why is plastic problematic?

The matter-munching sinkhole is a whopping 13 billion light-years away, so far that we see it as it was a mere 690 million years after the Big Bang. But at about 800 million times the mass of our Sun, it managed to grow to a surprisingly large size such a short time after the origin of the Universe. The find is described in the…
