Human: What do I need to know about how to buy sustainable seafood? Assistant: 
To buy sustainable seafood, it is important to be aware of where the seafood is coming from, what methods were used to catch the seafood, and if possible to choose seafood with the best environmental practices. Look for seafood labeled 'sustainable' or 'certified sustainable' and check the origin and species of the seafood. Additionally, it is best to buy local or domestic seafood if possible, and to support fisheries that have implemented fishery improvement projects to ensure sustainable harvesting methods.
