How much rubbish is in the ocean 2021?
There are 5.25 trillion pieces of plastic waste estimated to be in our oceans. 269,000 tons float, 4 billion microfibers per km² dwell below the surface. 70% of our debris sinks into the ocean’s ecosystem, 15% floats, and 15% lands on our beaches. In terms of plastic, 8.3 million tons are discarded in the sea yearly.
