A vast new analysis looked at 15 different food groups, like nuts, fish and red meat, ranking them based on how they influence health and the toll they take on the planet.

Advocates say farmed seafood is more sustainable than wild-caught. Critics say these farms pollute surrounding waters. Federal waters have been off-limits to aquaculture, but that may soon change.

Concerns over animal welfare have led to changes in recent years in how livestock are raised. But seafood has been missing from the conversation. One group aims to change that.

Earlier this month, thousands of Atlantic salmon escaped a net pen in Washington state, raising concerns from environmentalists and questions about farming non-native species. Here are some answers.

New research suggests there is space on the open ocean to farm essentially all the seafood humans can eat — and then some. But such volumes of fish and shellfish could not be grown without costs.
