This composite satellite image shows concentrations of planetary biomass. On land, forests and grasslands are indicated in green; at sea, plankton are shown in yellow and red. The areas of highest oceanic productivity are concentrated along coastlines and in regions of upwelling. Mid-ocean zones are nearly devoid of algae and most other life. These vast oceanic deserts, indicated in dark blue and purple, can be colonized without disturbing any preexisting ecologies.
