In this multi-award-winning film, Rob Stewart embarks on a global journey to uncover the grave dangers threatening the world's oceans -- and ultimately, humanity -- as well as to learn what it will take to reverse the challenges to life on earth. From the coral reefs in Papua New Guinea to the rainforests of Madagascar, Stewart's travels reveal that our fate is tied to even the smallest of creatures. Stunning scenes of underwater sea life bring viewers face to face with sharks and lemurs, into the microscopic world of the pygmy seahorse, and on the hunt with the deadly flamboyant cuttlefish. The footage in REVOLUTION also dramatically reveals evidence of ocean acidification caused by our passion for fossil fuels, resulting in empty stretches of expired coral reefs. In every previous mass extinction, coral reefs were the first eco-systems to be wiped out. One powerful segment summarizes the evolution of life on earth, putting into stark perspective the challenges human activity has created. Along the way, Stewart visits with experts to learn more about the threats to the planet, and attends a failed international conference, where he criticizes government leaders for offering token, ineffective nods to environmental sustainability. In the end, Stewart finds hope and inspiration when he encounters the new face of the environmental movement -- young people worldwide who are leading a global revolution to challenge leaders to take effective action to stem climate change and the dangers facing the planet.
