Deep-Sea Microplastics

According to a recent study, 270,000 tons of plastic waste are floating in the world’s oceans. That sounds like a lot, but the annual production of plastic is over a thousand times higher. So scientists are starting to wonder: Has the inventory of plastic in the oceans just scratched the surface? New samples from the bottom of the deep sea might provide an answer.

But the pain they cause is relatively harmless compared to the real problem: there are so many of these sea urchins around the Canary Islands now that they threaten the biodiversity of the ecosystem. I reported on the problem and how marine biologists are trying to contain the plague. The Hungry Sea Urchin weiterlesen
