清洁能源真的清洁吗？这部由Michael Moore监制的纪录片带领观众走进清洁能源的一线，细究清洁能源的设备制造方式和材料、使用年限、发电材料来源、以及背后的经济驱动力。本片也揭示了美国一些头号环保人士和环保组织在生物质能源等可再生能源令人疑惑和担忧的立场，以及环保运动和能源业的资助关系。当环保主义和资本主义手牵手，能源真的会更清洁吗？ 　　Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will this Earth Day — that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road — selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It's too little, too late. 　　Removed from the debate is the only thing that MIGHT save us: getting a grip on our out-of-control human presence and consumption. Why is this not THE issue? Because that would be bad for profits, bad for business. Have we environmentalists fallen for illusions, “green” illusions, that are anything but green, because we’re scared that this is the end—and we’ve pinned all our hopes on biomass, wind turbines, and electric cars? 　　No amount of batteries are going to save us, warns director Jeff Gibbs (lifelong environmentalist and co-producer of “Fahrenheit 9/11” and “Bowling for Columbine"). This urgent, must-see movie, a full-frontal assault on our sacred cows, is guaranteed to generate anger, debate, and, hopefully, a willingness to see our survival in a new way—before it’s too late. 　　Featuring: Al Gore, Bill McKibben, Richard Branson, Robert F Kennedy Jr., Michael Bloomberg, Van Jones, Vinod Khosla, Koch Brothers, Vandana Shiva, General Motors, 350.org, Arnold Schwarzenegger, Sierra Club, the Union of Concerned Scientists, Nature Conservancy, Elon Musk, Tesla. 　　Music by: Radiohead, King Crimson, Emerson, Lake & Palmer, Blank & Jones, If These Trees Could Talk, Valentina Lisitsa, Culprit 1, Patrick O’hearn, The Torquays, Nigel Stanford, and many more. 　　Donate: https://www.paypal.com/cgi-bin/webscr... 　　Website: https://planetofthehumans.com/ 　　FB: https://www.facebook.com/PlanetoftheH...

One of the first recorded images of a giraffe appeared in the drawings of the ancient Egyptians, who named it ‘sr’. In the 1990s, veterinarian Motke Levinson purchased four giraffes on behalf of two zoos. Upon their arrival in the same container to a port in the Red Sea, they were divided. Two were sent to an Israeli zoo while the others were sent to a Palestinian zoo. Living outside their natural habitat, their survival became an uphill battle at the zoos, and within years, they perished. This is just one of many stories that director Lea Harlaub ponders on. From the wall paintings of ancient Egyptians to exotic animal exports and modern-day safari tourism, this essay film takes us on a hypnotic journey to weave together the history of this majestic animal with the history of humanity.
