Greenpeace activists unfurl a banner at the headquarters of food distribution and retailer Jeronimo Martins group reading in Portuguese "Jeronimo Martins destroys our oceans". Greenpeace is demanding immediate action to preserve the world's fish stock and oceans and are targeting the supermarket Pingo Doce, part of the Jeronimo Martin group, for not improving their offer of sustainable seafood and ignoring all concerns raised about the world's oceans crisis.
