LEGACY

Chemical engineer and inventor Maria Telkes worked for nearly 50 years to harness the power of the sun, designing and building the world's first successful solar-heated modern residence and identifying a new chemical that could store solar heat like a battery. Telkes was undercut and thwarted by her (male) boss and colleagues at MIT, but she persevered. Upon her death in 1995 Telkes held more than 20 patents, and now she is recognized as a visionary pioneer in the field of sustainable energy whose work continues to shape how we power our lives today.

In 1962, Rachel Carson's book Silent Spring opened America's eyes to the dangers of pesticides and man's place in nature. This episode of the "Before/After" series dives into the genesis of a poetic and powerful text, which inspired modern environmentalist thought.

As the most dammed, dibbed, and diverted river in the world struggles to support thirty million people and the peace-keeping agreement known as the Colorado River Pact reaches its limits, WATERSHED introduces hope. Can we meet the needs of a growing population in the face of rising temperatures and lower rainfall in an already arid land? Can we find harmony amongst the competing interests of cities, agriculture, industry, recreation, wildlife, and indigenous communities with rights to the water? Sweeping through seven U.S. and two Mexican states, the Colorado River is a lifeline to expanding populations and booming urban centers that demand water for drinking, sanitation and energy generation. And with 70% of the rivers’ water supporting agriculture, the river already runs dry before it reaches its natural end at the Gulf of California. Unless action is taken, the river will continue its retreat – a potentially catastrophic scenario for the millions who depend on it.

With a hybrid style blending political essay and road movie, this documentary by Santiago Bertolino takes us into the heart of the Amazonian reality. Following Marie-Josée Béliveau, an ecologist and ethnogeographer, they journey together along the 4000 km from the mouth of the Amazon River in Brazil to one of its sources in Ecuador where they meet with the guardians of the forest. As a result, we witness powerful and spontaneous testimonies from local communities who are doing everything to preserve what remains of their lands, which are disappearing due to the inexorable advance of Western modernity.

The Pullars are the last family using traditional methods to fish for wild Atlantic salmon off the coast of Scotland. When these include killing seals, the salmon’s natural predators, conflict erupts. Animal activist groups Sea Shepherd and Hunt Saboteurs oppose the Pullars at every turn, despite the legality of the fishermen’s actions and the consequences to their livelihood. Challenging preconceptions, this ambiguous doc puts modern environmentalism under the microscope.

A look at Britain's beloved canal network via a fact-filled cruise along the first superhighways of the Industrial Revolution. In the age before mechanisation, a frenzy of canal-building saw a new army of workers carve out the British landscape, digging out hundreds of miles of waterways using picks, shovels and muscle.

One of the world’s greatest ancient enigmas, the Nazca lines are a dense network of criss-crossing lines, geometric shapes, and animal figures etched across 200 square miles of Peruvian desert. Who created them and why? Ever since they were discovered in the 1920s, scholars and enthusiasts have raised countless theories about their purpose. Now, archaeologists have discovered hundreds of long-hidden lines and figures as well as evidence of ancient rituals, offering new clues to the origins and motivations behind the giant desert symbols.

In the same vein as Meri's other documentations, this one takes advantage of the glasnost policy to discuss the social and ecologic impact of the Russian oil industry on the natives and the lands they inhabit.

In the racially turbulent UK of the early 70s, a group of black musicians came together in South London with a common love of rhythms and a message of peace. Cymande – with the dove as their symbol – combined jazz, funk, soul and Caribbean grooves to form a unique sound. Despite success in the USA they faced indifference in their native Britain, becoming disillusioned and disbanding. But the music lived on, as new generations of artists imbibed and reworked their pioneering sounds in fresh ways. From Soul II Soul to De La Soul, MC Solaar to The Fugees, the Dove had spread Cymande's message far and wide, prompting their return after forty years. This is their story.
