The documentary film A Sea Change, broadens the discussion about the dramatic changes we are seeing in the chemistry of the oceans, and conveys the urgent threat those changes pose to our survival, while surveying the steps we can take to reduce the severity of climate change. The film's protagonist, Sven Huseby, asks how will he explain to his oldest grandchild, Elias, what is happening to the oceans and their ecosystems. A Sea Change is both a personal journey and a scientifically rigorous, sometimes humorous, unflinchingly honest look at reality. It offers positive examples of new technologies and effective changes in human behavior that we all must choose before the oceans are lost.
