How can you tell when it's Christmas in the ocean? By the cinnamon & vanilla flavoring the water. Holiday cookie baking shows up in Puget Sound, after the cookies are eaten and...well...processed.
Digging deeper, researchers estimate that Seattle desert lovers ate about 200,000 cookies per day containing cinnamon & vanilla.
It's incredible how our habits influence oceans, even our cookie habits. Previously, we've heard about caffeine, antidepressants, birth control hormones, and antibiotics showing up in Seattle-area streams, with possible effects on fish and other animals.
Do the cookies matter? Smell is important to some fish, and spices are used because of their pungency, so who knows? Fish probably appreciate the end of the season and the seasoning.
