Lily wants to help the world. She wants to stop the Earth from getting hotter and the Arctic from getting smaller.
She’s in a society called the Green Heroes . They help endangered animals.

Polar bears live in the Arctic. They live on the ice and swim in the sea. They catch and eat other sea animals like seals, fish or small whales. Polar bears have problems because the world is hotter than it was before. Oceans are hotter and the ice cap is smaller so polar bears are losing their habitat. Now it’s more difficult for polar bears to fish for food or look after their babies if they haven’t got ice to live on.
