    Excerpt from the Geographical article:

    ‘Mangrove ecosystems are rare – they cover a small area of the globe,’ says one of those authors, Dr Hanneke Van Lavieren of the UN University’s Institute for Water, Environment and Health. ‘That makes them even more at risk from aquaculture and development. You find mangrove forests in areas perfect for shrimp farming. The water is brackish, they create sheltered areas, the water is flushed naturally. But the intensive nature of aquaculture makes it unrealistic for mangroves to carry out their natural role of filtering out pollution.’
