What is call within your heart? Is it softly speaking to you? Is it shouting? There is a call in each of our hearts sending us on a unique mission to make our world a better place. Listen to your heart’s call, act on it, and you will astound yourself and others with what you are able to accomplish. Lewis Pugh’s deep call is to make us aware of the effects of climate change on our planet. In this YouTube video, Mr. Pugh swims in below freezing water as he becomes the first person to swim across the North Pole. It is his unique call and response that raises attention to climate change.
