Leonardo DiCaprio’s Climate Change Documentary, ‘Before the Flood’ is a staggering journey. Both terrifying and quietly hopeful, it outlines the problem of climate change in a clear and easy to understand way. It explains why there is so much disinformation around about the issue (greedy fossil fuel corporations and the politicians they own). And it also offers some practical steps we can take now, if we want to avoid widespread chaos within the next forty years (or less, if some of the more pessimistic estimates are correct). Climate change is providing us with the perfect catalyst to transform into a sustainable world. Let’s take the necessary steps, before it is too late.
