Clip Description

Beaches can be enchanting and exciting places to visit. It can be very sad to witness the beauty of a beach spoiled by human waste – especially plastic pollution. Thousands of marine animals worldwide have been affected by plastic pollution, including sea turtles, seabirds, and marine mammals.

In this fascinating clip, children and adults have come together to clean up the beaches close to their homes on a stretch of Scotland’s coastline. Armed with litter grabbers, rubber gloves and bins, they attempt to remove plastic bottles, bags and other junk items scattered amongst the sand and seaweed. What do you think motivates this group of ‘eco warriors’ to clean up beaches in this way? Watch the clip to find out.

Quick Whiteboard Challenge
