Computer simulations predict that plankton growth will become unstable when the supply of nutrients is reduced. This may have a negative impact on the food chains of the oceans and on uptake of the greenhouse gas carbon dioxide into the oceans. Scientists of the Universiteit van Amsterdam and CWI (the Netherlands) and the University of Hawaii (USA) presented their results in Nature of 19 January 2006.
