Before the Flood - Trailer | National Geographic

We've known about this for decades, for over half a century. Try to have a conversation with anyone about climate change; people just tune out. Climate change, climate change, CH! The problem seems to be getting worse and worse and worse. The truth is, the more I've learned about this issue and everything that contributes to the problem, the more I realize how much I don't know.

Oh my God, look at how violent that is! Paradise that has been degraded and destroyed; we're knowingly doing this. I just want to know how far we've gone and if there's anything we can do to stop it. The US has been the biggest emitter of greenhouse gases in history. You're a fossil-addicted country. We are doing more in investment in solar today than the US. [Music]

Is half the people in office still don't believe in climate change? Why do you think there is such opposition about the science? I think it's politics. People are so arrogant to think they can change climate. Environmental issues have become the biggest reason for mass demonstrations. We want to hold them accountable.

This is the most important issue of our time. The question is, can we change our course in time? You need 100 gigafactories to transition to sustainable energy. That would make the United States the whole world's energy. That sounds manageable. All that I have seen on my journey shows us we had the means of stopping this devastation.

Politicians do what the people want them to do. Once the American people are convinced, the politicians will fall in line very quickly. If we keep pushing, there's no reason why we can't solve this problem. The world is now watching. We ask you to protect it; are we and all living things we cherish our history? [Music]
