The world’s oceans and their sediments are one of the least explored habitats for their total biodiversity, and taken together with freshwater lakes, rivers and wetlands, constitute a major part of the total biodiversity on Earth. Yet all are under threat as never before as a result of the effects of climate change and human exploitation, with even such widely eaten fish as the North Sea Cod endangered, coral reefs being bleached, and anurans becoming extinct on an unprecedented scale.
