Currently, oysters are not so much top of mind, but rather top of taste with their salty liqueur served up on the half-shell at happy-hours. And so, Sammy Spat and the Big Rescue was written to help change that reality by increasing oyster literacy for our collective betterment. Why? Because oysters are critical to protecting our oceans on which all life depends.

Today, approximately 85% of their reefs systems are gone worldwide, along with the benefits their systems provide. In the past, civilizations grew along side oyster reefs. This humble bi-valve has been helping humans survive since our beginning. Now, we need to return the favor. By supporting oyster aquaculture and reef restoration efforts around the world, oysters, in turn, can continue to do what they have always have done – protect our oceans, and protect us.

In 2015, she organized the 6th International Oyster Symposium, which was held for the first time in the USA. She holds degrees from Southern Illinois University and from Minnesota State University with an MS in Educational Leadership. Her love for the environment is undeniable. And creating ways to increase oyster literacy drives her. For Ms. Dowcett, the “world is her oyster” not so much for the taking, but for the sharing and caring.
