It’s not a person. It’s a Bubble Barrier. Every minute, the equivalent of one full garbage truck of plastic trash is dumped in the sea. Some bright sparks have come up with an ingenious way to stop this happening and it involves a wall of bubbles.

Friendly to fish and ships, the Bubble Barrier intercepts plastics in rivers and canals, and stops them entering our ocean. Currently being trialled in Amsterdam, this is more than a thought bubble it’s bubbles for positive change.
