The majestic whales of the great oceans fill us with delight and hope, but science is now showing that these amazing creatures have a vital role to play in both the health of the oceans and the atmosphere.
We all know that whales eat krill but as the whales declined, so did the fish and krill. In fact, killing whales led to less food in the oceans. This is because whales help to sustain the entire living system of the ocean – more whales means more fish.
But even more amazingly, the plant plankton, which grows more profusely due to whales, removes carbon dioxide from the atmosphere and stores it at the bottom of the oceans.
Enjoy this beautiful video on the importance of whales.
