How is climate change affecting polar bears at the North Pole?
The ice at the North Pole is getting thinner and melting – this means that there is less ice for the polar bears to travel on in the hunt for food. The change in temperature is also disrupting the natural food chain at the North Pole. Disrupting the food chain means that the polar bears (and the other animals in the food chain) have less to eat. In the Arctic Ocean, the basic food chain is: Algae under the sea ice are food for small organisms called plankton –> Plankton are food for Arctic codfish –> Ringed seal eat cod –> Polar bears eat ringed seals. PSHE • As a whole class discuss how climate change affects us. Lead pupils to the conclusion that our communities have adapted to seasonal cycles and climatic conditions. Introduce the idea of potential impacts. What would happen if our climate changed dramatically? Ask the pupils to think of a climatic change and how that would affect them, such as: less snow would mean people could not ski as much; more rain would mean that pupils c
