Home the Movie

Former actor Yann Arthus-Bertrand directed this visually astonishing portrait of the Earth as seen from mesmerizing aerial views. Home is not the first documentary to survey our planet from the air, but Arthus-Bertrand brilliantly and dreamily captures the miraculous linkage within delicate eco-systems. For viewers whose eyes glaze over at descriptions of the way Earth recycles energy and matter, Home underscores the beautiful and awesome reality of that complex process. Narrated by actress Glenn Close (in this English-language version), Home begins by exploring and clarifying the natural history of water, sunlight, and the role simple life-forms such as algae played (and still play) in making the planet hospitable to more evolved, living things. As the film moves along, it also has a way of rebooting one's lazy assumptions about familiar phenomena. The Grand Canyon, for example, might be a fantastic sight to behold, but it's also a collection of billions and billions of shells compressed under Earth's oceans long ago. The carbon trapped in the Grand Canyon was drained from the atmosphere, helping--once again--oxygen-dependent life to develop.

Similarly, plant life, Home tells us, broke up the water molecule and released oxygen into the atmosphere. Everything is linked, everything is part of a grand machine--the film makes this clear in scores of ways, and not just by telling us. Arthus-Bertrand reveals the intricate, breathtaking designs and patterns of glaciers feeding rivers, of animals feeding on plant life so more plant life can grow, of Australia's great Coral Reef's role in keeping the ocean in eco-balance. Of course, a big part of the story is the impact short-sighted humans have on these systems: the way we overfish, or drain deserts of scarce fossil water, or turn non-farming lands into perverse engines for agriculture. There is much to be alarmed at watching Home, but there is much to move one as well. --Tom Keogh

Call of Life: Facing the Mass Extinction

Call of Life: Facing the Mass Extinction

is a documentary that enlists the expertise of scientists from around the world. They conclude that if current trends continue, within a few decades at least HALF of all plant and animal species on Earth will disappear forever. “Call of Life: Facing the Mass Extinction” is the first feature documentary to investigate the growing threat to Earth’s life support systems from this unprecedented loss of biodiversity. Through interviews with leading scientists, psychologists, historians, and others, the film explores the causes, the scope, and the potential effects of the mass extinction, but also looks beyond the immediate causes of the crisis to consider how our cultural and economic systems, along with deep-seated psychological and behavioral patterns, have allowed and continue to reinforce the situation, and even determine our response to it. “Call of Life” tells the story of a crisis not only in nature, but also in human nature, a crisis more threatening than anything human beings have ever faced before.

Teddy Cruz: Architectural Sustainability from the Bottom Up

As the world's cities undergo explosive growth, inequality is intensifying. Wealthy neighborhoods and impoverished slums grow side by side, the gap between them widening. In this eye-opening talk, architect Teddy Cruz asks us to rethink urban development from the bottom up. Sharing lessons from the slums of Tijuana, Cruz explores the creative intelligence of the city's residents and offers a fresh perspective on what we can learn from places of scarcity. Teddy Cruz looks for clues to the "city of the future" in the emerging urban areas of today.He works at the crossroads of architecture, urbanism, policy and art and has looked deeply, over many years, at the Tijuana-San Diego area spanning the US-Mexico border -- a thriving, high-density, high-activity zone of trade and urban relationships -- and at other southern cities. And he suggests that the modern, highly planned cities of the developed world have much to learn from these developments. The informal shops, garages and neighborhoods of a boomtown are built to maximize "social flow" -- because buildings are easy to put up and modify, they can respond exactly to the inhabitant's needs, connecting them to the community and the city. In collaboration with community-based nonprofits such as Casa Familiar, Cruz and his team also explore new visions for affordable housing, in relationship to an urban policy more inclusive of social and cultural programs for the city. In 1991, Cruz received the Rome Prize in Architecture; in 2005 he was the first recipient of the James Stirling Memorial Lecture On The City Prize. Born in Guatemala, he is a professor in public culture and urbanism in the Visual Arts Department at University of California, San Diego. "Where others saw poverty and decay, he saw the seeds of a vibrant social and architectural model." The New York Times --Taken from "Teddy Cruz: How Architectural Innovations Migrate Across Borders."
