NASA mapped the annual cycle of all plant life on the planet in this animated map.
Satellite instruments reveal the yearly cycle of plant life on the land and in the water. On land, the images represent the density of plant growth, while in the oceans they show the chlorophyll concentration from tiny, plant-like organisms called phytoplankton. From December to February, during the northern hemisphere winter, plant life in the higher latitudes is minimal and receives little sunlight.
