Leonardo Dicaprio, the host of this video and he has gained respect worldwide for being a tireless advocate for educating us about viable ways for reversing Global Warming. In this video he provides many facts to paint an accurate picture of how dire the present global warming crisis is and why inaction is not a viable option. Dicaprio shows how our addiction to oil might push us over the edge.
