The film focuses on events from flooding in Miami and the Philippines, the worst drought on record in Syria, to air pollution so bad in some parts of China that life expectancy has declined by six years.

The documentary kicked off the 2017 Sundance Film Festival, where it was met with overwhelmingly positive reviews.
