CSIRO (Commonwealth Scientific and Industrial Research Organisation), an Australian government agency, has recently found that the world sea floor is littered with more than 14 million tonnes of microplastics.
These microplastics have entered the floor through the breakdown of masses of rubbish entering the oceans annually.
This is the first time the sea floor microplastic study has been carried out.
Microplastics are small pieces of plastic that are of size 5 mm or less.
They are mostly derived from the breaking down of larger plastic items.
