Scientists have dubbed the dramatic rise the "Blue Acceleration." The researchers from the Stockholm Resilience Centre, Stockholm University, synthesized 50-years of data from shipping, drilling, deep-sea mining, aquaculture, bioprospecting and much more. The results are published in the journal One Earth, 24 January.

The scientists say the largest ocean industry is the oil and gas sector, responsible for about one third of the value of the ocean economy. Sand and gravel are the ocean's most mined minerals to meet demand from the construction industry. As freshwater become an increasingly scarce commodity, around 16,000 desalination plants have sprung up around the world in the last 50 years with a steep rise since 2000, according to the analysis.
