Dosbarth Fir have been finding out about the impact that different types of pollution can have on our oceans. The children have looked at images of our local beaches and have realised that littering can cause huge problems. They have listened to stories and have taken part in experiments to see how difficult it can be to clean up an oil spill and other types of pollution. The children considered how our actions can help ensure our environment is safe for all. Da iawn Dosbarth Fir.
