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.
A Sea Change documents how the pH balance of the oceans has changed dramatically since the beginning of the Industrial Revolution: a 30% increase in acidification. With near unanimity, scientists now agree that the burning of fossil fuels is fundamentally reshaping ocean chemistry. Experts predict that over the next century, steady increases in carbon dioxide emissions and the continued rise in the acidity of the oceans will cause most of the world's fisheries to experience a total bottom-up collapse--a state that could last for millions of years. 2009, 84 minutes.
