An interesting concept - but why is it important? The point being made is that the disappearance of polar bears would herald singificant changes in our world. The Arctic is home to many different kinds of animals and now their habitat is melting at an alarming rate. As the Arctic ice melts, polar bears are threatened with extinction. What are the terrible consequences if polar bears truly disappeared? Outstanding artwork by artist and writer Lily Williams explores how such a loss would affect other environments and animals across the planet . It's a book to make children think about climate change, conservation and the importance of ecosystems.
