Watch Five Ways to Save the World

Five Ways to Save the World is a 2006 documentary about climate change. However, this isn't simply a gloomy look at the world's state of affairs. Instead, the film aims to solve the crisis of climate change. Among the ideas outlined in this film to combat against global warming is a giant shade in space to block out the sun's most harmful rays. Another plan discussed is to shoot off sulfur-filled rockets into the atmosphere to act as a thin veil of sunscreen. The cause of global warming, carbon dioxide, is also discussed in this documentary, along with outlandish yet possible solutions that could quite possibly save humanity.
