David Attenborough presents a documentary series exploring how animals meet the challenges of surviving in the most iconic habitats on earth.

"Ecumenopolis: City Without Limits" tells the story of Istanbul and other Mega-Cities on a neo-liberal course to destruction. It follows the story of a migrant family from the demolition of their neighborhood to their on-going struggle for housing rights. The film takes a look at the city on a macro level and through the eyes of experts, going from the tops of mushrooming skyscrapers to the depths of the railway tunnel under the Bosphorous strait; from the historic neighborhoods in the south to the forests in the north; from isolated islands of poverty to the villas of the rich. It's an Istanbul going from 15 million to 30 million. It's an Istanbul going from 2 million cars to 8 million. It's the Istanbul of the future that will soon engulf the entire region. It's an Istanbul nobody has ever seen before.
