There's one type of seafood that's affordable, nutritionally dense and even helps improve the environment: mussels. According to the National Library of Medicine, mussels are a great source of protein and Omega-3 fatty acids, and they produce far less greenhouse gas emissions in comparison to other protein sources such as beef, lamb and pork. Plus, they are "filter feeders," which means they remove impurities in the water around them. What a win-win!
