Marine Litter: How Clean are our Seas?
Marine Litter: How Clean are our Seas? from the Marine Conservation Society gives an overview of the litter in our seas, looking at why it’s an important topic and focusing particularly on how animals are affected by litter.
It is the first in a series of lessons available on their website: other lessons in the series explore The Plastic Plague, engage pupils with some Art-ivism and set a plastic challenge. Highly recommended.
