NOAA has released an interactive map of the Earth's vegetation. The Green Vegetation map was created using information from the VIIRS sensor aboard the NASA/NOAA Suomi NPP satellite.
The nighttime greenest areas on the map are the locations alongside the lushest vegetation. The map uses a pale color for the Earth's oceans. I'm guessing this is because if 75% of the planet was colored blueish this would detract from the vegetation beingness highlighted on the map.
You tin read to a greater extent than nearly the vegetation information together with how the map was created on the NOAA website.
