Actress Jessica Chastain recites a heart-rending poem to a lost love in this gorgeously filmed PSA from The Nature Conservancy. And though it sounds from the tremble in her voice that it's addressed to some guy she cheated on, as the film progresses it becomes clear the lost love is nature itself.

Directed by O Positive's Peyton Wilson, the spot was made in the Sierras and features Chastain's narration of the poem "Our Nature" (by Matthew Dickman) as we see a young woman walking outside and rediscovering her environment. It directs viewers to a website for the California-based non-profit where they can share views on the subject of nature, promoting the hashtag #cantlivewithoutnature.
