The butterflies of the sea, fragile victims of carbon dioxide

Pteropods are tiny little creatures, about the size of a child's fingernail or less, upon which most of the creatures in the sea depend on. These lovely little sea butterflies are the main food source for many fish, including important commercial ones such as salmon.

And they are in terrible danger. Their fragile little shells are beginning to cloud and crack and dissolve in the increasing levels of acidity in our ocean. Our oceans are sucking up our CO2 and it is killing them.

A Sea Change - Imagine A World Without Fish

Ocean acidification threatens over one million species with extinction--and with them, our entire way of life.


This is an award-winning film, made by a couple of grandparents for their granchild. It follows the grandafather's discovery of the existence of pteropods and his journeys across the US, Canada, Alaska and Norway learning about them for the sake fo his grandson.
