Microplastics on sea floor

October 12 , 2020 1379 days 911 0
  • 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.
