How can we stop plastic flowing into our oceans? Dutch inventors have one solution, pulling plastic from the water using a ‘net’ made from bubbles.

Also on the programme - how sound could be used to help restore coral reefs in Australia. Scientists found playing the sounds of a healthy reef under water, could attract fish back to the site. They hope to combine this with coral seeding to rebuild reefs teeming with life.

And our last solution keeps with the water theme - looking at a hand-cranked washing machine that makes laundry quicker and easier for some of the poorest women in society.
