What a great opportunity to learn about life under the water at the Long Wharf Nature Preserve. Mary Beth Decker, researcher and lecturer at Yale, taught us about all the reasons we should be thanking plankton! Plankton gives us about half of the air we breathe, provides food for marine life, and was one of the earliest life forms! I have another to add: thank you, plankton for providing such an awesome lesson about living systems! Thank you, Plankton!
