Jaume Terradas' notes
The West world, with its desire for expansion and exploration of new and unknown territories, has deprived indigenous communities of their traditional methods of life and culture. The Arctic tribes have not either been an exception.
Los Angeles and its great urban area (more than 18 million people) are in water suply problems since long time ago. At the begining of the 20th century, Owens Valley was drained among huge hiden economic interests that inspired the film Chinatown.
Jaume Terradas explains how an error in channeling the water of the Colorado River in California created a large artificial lake that, now, is endangered by the great water demand from the crop fields and nearby cities.
