Ocean acidification is an issue that may not be on everyone’s lips, but its causes, solutions, and dire impacts if gone unaddressed are the same as climate change. A Sea Change (check the trailer below the fold) is a new documentary on the subject that follows retired educator Sven Huseby on a mission to Norway and Alaska to investigate the problem of too much atmospheric carbon and its detrimental acidifying effect on the marine food chain, through the lens of his sweet relationship with an ocean-loving grandson. The film won acclaim from the audience at its DC Environmental Film Festival premiere last month, so watch for it on a screen near you soon.
