Action hero, politician, climate crusader and Years of Living Dangerously executive producer Arnold Schwarzenegger sets out to explore the military's relationship with a changing climate, including how our armed forces are dealing with an increasing number of climate-related disasters and how the military is working to reduce its own carbon footprint. Schwarzenegger travels to Kuwait to visit soldiers and travel in a fuel convoy (where more than 3,000 soldiers have been killed or injured since 9/11). He learns how serious a threat the military perceives climate change to be, talks to top-level military leaders and meets the brave men and women who are dealing with climate change threats and disasters on the front lines. The battle to save the Amazon in Brazil - the "lungs of the planet” - is the ultimate race against time. There are ever-increasing threats from cattle ranching, drought, deforestation, massive hydroelectric dams and illegal mining. Supermodel and activist Gisele Bündchen travels to her home country to see the extent of the damage and investigates what's being done to save the rainforest for all of us. Deep in the Amazon, she joins the national environmental police on a mission to put an end to illegal deforestation; in Alta Floresta, she meets with Greenpeace for a flyover of the forest, which reveals huge patches of deforested land, logs piled high on trucks and barges, drought-stricken fields, burnt rainforests and vast cattle ranches that were once lush, thousand-year-old tropical rainforests.
