Pollution: How 'seabins' are helping to fight pollution in Sydney's waterways
We all know waste in the ocean is a big problem, but now one aquarium in Sydney, Australia, thinks it might have found very clever new solution.
People there have been been helping to install a very special type of bin in the waterways around the city, including one at the aquarium.
Seabins are floating rubbish bins that collect litter from the sea 24 hours a day, 365 days a year.
