Among Giants (2011)

In the midst of California's coastal redwood region, Green Diamond Resource Company continues to clearcut redwood forests, devastating habitats and leaving scars across the land. Farmer, a direct action environmental activist in his late 20s, decides to tree-sit in the McKay Tract -- a 60-acre grove of ancient redwoods that is home to spotted owls, deer, flying squirrels, and countless other life forms.
