Wish it were seagrass Sunday. That's my Blue Carbon Fun Day-with a wink and a nod to the 80's band The Bangles, Susan Di Giulio gets the low down from Dr. Emily Pidgeon of Conservation International, about damage that's been done to the true heroes of sucking carbon out of the air we breathe and trapping it below marshes and oceans. Pidgeon is the leader of the Blue Carbon initiative, which wants to save the places the world depends on for life.
