Leonardo DiCaprio’s great documentary presents the topics of human ecology, environmental destruction and global climate change and how humans have directly and swiftly caused ecological change on a global scale. The films’s initial goal is to raise awareness of the issues associated with these topics and their implications for the future, but the larger goal is to show that human’s, as a species, can switch their implied role in nature from one that is dominant and hostile to it, to one that is integrated and beneficial to the one and only planet that is known to support life.
