There’s more than one way to be an environmental warrior. And some approaches work better than others. Elemental follows the stories of three environmental advocates united by their deep connection with nature and driven to confront some of the most dire ecological issues affecting their respective communities. This isn’t only a story about plight and pollution, however. Rather, Gayatri Roshan’s and Emmanuel Vaughan-Lee’s documentary works best as a character-driven study of eco-activism’s do’s and don’ts.
