Extracting diamonds is no easy feat. By 50 degrees below 0 and polar winds, thousands of men work in giant open-air mines of 1,5 km diameter. These holes the size of lunar craters are excavated by huge bulldozers that dig sometimes 300 meters deep into the permafrost and then into black lava rock of over 53 million years old.

Planet of the Humans (2019), 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 (2004) and Bowling for Columbine (2002)). 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.

African elephant Shani and her spirited son Jomo set out on an epic journey with their herd, traveling hundreds of miles across the vast Kalahari Desert, from the Okavango delta to the Zambezi River, just as countless generations of their ancestors have done before. Shani and her family are among the last elephants on earth to make these lengthy migrations. She's mother to wide-eyed, one-year-old Jomo, who has yet to experience a migration, and at 40 years old, she is next in line as herd matriarch, a position currently held by her older sister Gaia. Gaia's herd is among countless species - from hippopotamus to lechwe to baboons - that rely upon the life-giving water that flows from the mountains and transforms the heart of the desert into a green oasis known as the Okavango delta. But the season's end is near and soon there will be a mass exodus. Nothing on Earth is more precious to life than water. And perhaps nowhere is this more apparent than the Kalahari desert in southern Africa, one of the driest places on the planet. The water is receding and paradise will soon turn to dust as the delta becomes a series of vanishing pools. Gaia instinctively knows she must lead the herd directly into the baking Kalahari desert, before the remaining water holes dry up. The herd's success will depend on her experience and wisdom, which has been handed down over many generations. Just as the saying "an elephant never forgets" implies, these massive mammals have a deep connection to their past. Gaia will take her family down ancient elephant paths, networks of lines and circles - the circles being water holes the family will desperately need to cross the vast desert. Along the way, they'll seek nourishment from sources such as moisture-rich mopane leaves and baobab tree trunks filled with rainwater. As they near their destination, the herd must cross the mighty Zambezi River to reach the safe haven for which they've been searching. They must enter the shallows, where crocodiles prey upon elephant calves like Jomo, and fight a ferocious current that could draw them into the world's greatest waterfall, Victoria Falls. Fortunately, the herd has the strength and stamina to succeed and can rest while enjoying unlimited water and all the palm nuts they can shake from the trees. But within a few short months, food is scarce and the water begins its voyage back to the Okavango delta. The family must traverse the wilds of Africa, yet again. The march back to the delta will be no easy task, as the Angolan flood waters are early this year and the herd will need to make quick time. However, the emotional bonds between elephants are as strong as those between humans and the strength of family has gotten them this far. Together, Gaia, Shani, Jomo and family dare to take the shortest route - through lion country.

The Pollinators is a cinematic journey around the United States following migratory beekeepers and their truckloads of honey bees as they pollinate the flowers that become the fruits, nuts and vegetables we all eat. The many challenges the beekeepers and their bees face en route reveal flaws to our simplified chemically dependent agriculture system. We talk to farmers, scientists, chefs and academics along the way to give a broad perspective about the threats to honey bees, what it means to our food security and how we can improve it.
