How can drones help to fight our plastic waste problem?

If plastic ends up on beaches it can easily get into the sea, and cause harm to fish and animals.

This issue is that no one knows where all the plastic is.

So, one charity had the idea of using drones to find out.

The drone flies high up in the sky, and takes pictures of the land below.

Any plastic in the photos can then be tagged so it can be removed.
