Are we in for a "Sea Change"?

Imagine a world without fish?” That’s the question asked by a new documentary called A Sea Change set to air on American TV Sept. 26, on Planet Green at 8 pm EDT.  Tune in if you can, because this is important stuff.  This is the first documentary  to explore in depth  the evil twin of global warming–ocean acidification. In concert with a warming climate, more acidifying oceans can mean the end of life for millions of species on earth, including, potentially, us.

According to Science Daily , “Ocean acidification is linearly related to the amount of CO2 we produce. CO2 dissolves in the ocean, reacts with seawater and decreases the pH. Since the industrial revolution, the oceans have become 30 percent more acidic (from 8.2 pH to 8.1 pH).”

The ocean absorbs about a third of the CO2 emitted into the atmosphere from the burning of fossil fuels. However, as CO2 dissolves in seawater, the pH of the water decreases and acidification occurs.

80% of earth’s surface is covered by water so acidification affects more than you might imagine, from coral reefs, to microscopic plankton, sharks, shellfish, whales, seals, turtles and sea birds.  It is already affecting you in the depletion of food fish species and the dying off of coral reefs. In the future, coupled with global warming it could affect the very existence of  your children and grandchildren.

An Important Documentary

A Sea Change is an important documentary that not only sheds new light on an important aspect of climate change, but also highlights the touching journey of the film’s co-producer Sven Huseby on his quest to discover what is happening to the world’s oceans.

Can you imagine a world without fish?

After reading Elizabeth Kolbert’s “The Darkening Sea,” Sven becomes obsessed with the rising acidity of the oceans and what this “sea change” bodes for mankind. His journey takes him to Alaska, California, Washington, and Norway as he uncovers a worldwide crisis  most people are unaware of. Speaking with oceanographers, marine biologists, climatologists, and artists, Sven discovers that global warming is only half the story.  Excess carbon dioxide is dissolving in our oceans, changing sea water chemistry. The more acidic water makes it difficult for tiny creatures at the bottom of the food web to form their shells. The effects could work their way up to the fish 1 billion people depend upon for their source of protein.

Lets try to make sure as many people as possible see this film.  Check the Planet Green Website to find the Planet Green channel number in your area. Save the date (Saturday, September 26th at 8pm EDT) and tell your friends.

This is a film that makes a personal as well as a universal statement that cannot be ignored.  Once you have met Sven and accompanied him on his journey of oceanic discovery, you will never be the same again.  Watch the trailer below and you will see what I mean.
