This video, with words by writer and environmental, social justice and political activist George Monbiot, show us the importance of preserving animals at the top of the food chain. Many people believe that killing whales would leave more fish for us. Monbiot shows us that is not true. In fact, whales not only eat the fish and plankton, they also keep them alive. Among their many benefits, whales serve the environment by facilitating the grown of plant plankton, which in turn, absorbs carbon from the atmosphere. More whales = more fish and krill. More whales are good for both the sea and the atmosphere.
