Polar meltdown

"Following reports of a polar bear found dead near an Alaskan village, Dr Fisher is sending Ben and Zoe, Wild's number one operatives, to investigate. It's highly unusual for a polar bear to come so close to human habitation and this suggests something is seriously wrong."
"Following reports of a polar bear found dead near an Alaskan village, Dr Fisher is sending Ben and Zoe, WILD's number one operatives, to investigate. It's highly unusual for a polar bear to come so close to human habitation and this suggests something is seriously wrong. But the twins' mission takes another turn when they discover that the dead bear had recently given birth. This means there is an orphaned cub out there. Will Ben and Zoe find it in time? Suggested level: primary, intermediate."
"The twins Ben and Zoe are sent to an Alaskan village in the far north to investigate the death of a mother polar bear and find and rescue her two orphaned cubs."
