The gentle giants quietly saving our planet
An unusually large collection of humpback whales has been spotted feeding off the coast of Australia. They could be key to fighting the climate crisis.
It is one of the greatest wonders of nature. There are over one hundred humpback whales. And they caught it on film for only the second time ever. And they are at the surface of the water, eating.
This huge group is called a megapod. Scientists saw one off the Australian coast. They caught it on film for only the second time ever. Just 60 years ago, humpback whales were nearly extinct. Humans used to hunt whales. The meat was a popular dish and the blubber was used for soap.
If whales are returning, returning, it could be a good sign for the climate. Whales help to provide food for up to 200 ocean
species. Plus, they store up to 33 tonnes of carbon in their bodies. The more whales there are, the less harmful CO2 there is in our air.

Build the Change Challenge
Humpback whales play a huge role in the ocean ecosystem – but they are in danger. In this challenge, you will design a new ocean sanctuary to save the whales.
Step 1: Come up with a design. What features will it include? Why will the whales enjoy living there? How will it keep them safe?
Step 2: Create your sanctuary! You can draw a picture of it or, if you have time, use craft materials and LEGO® bricks to make a real version of your whale habitat.
