Microplastics Have Invaded The Deep Ocean — And The Food Chain

The largest habitat for life on Earth is the deep ocean. It’s home to everything from jellyfish to giant bluefin tuna. But the deep ocean is being invaded by tiny pieces of plastic — plastic that people thought was mostly floating at the surface, and in amounts they never imagined.

A new study shows that microplastic particles are not only common from the surface to the seafloor, but they’re also being eaten by animals and incorporated into marine food webs. The most abundant types of plastic found in the water samples match those commonly used in consumer products. Most plastic waste comes from land, although it may travel far on ocean currents.

Earth recycles ocean floor into diamonds

Most diamonds are made of cooked seabed. The diamond on your finger is most likely made of recycled seabed cooked deep in the Earth. Traces of salt trapped in many diamonds show the stones are formed from ancient seabeds that became buried deep beneath the Earth’s crust, according to new research.
