A Sea Change (2009)

Award-winning filmmaker Barbara Ettinger puts a human face on the realities of global warming and ocean acidification in this eye-opening document of one man's quest to learn more about his generation's environmental legacy. Although he's an environmentalist, native Norwegian Sven Huseby is a grandfather, too. And he's increasingly concerned about the kind of world his 5-year-old grandson, Elias, will inherit.
