I want to know the answer to the following question:
Where are the most threatened ecosystems found?
All the background I'm provided with is that "" At present, the most threatened ecosystems are found in fresh water, according to the Millennium Ecosystem Assessment 2005, which was confirmed by the "Freshwater Animal Diversity Assessment", organised by the biodiversity platform, and the French Institut de recherche pour le développement (MNHNP).". Is that enough to answer the question?
