The biodiversity of the Tropical Rainforests. The great tree studded grasslands of the African Savannah. The summer-parched Scrublands of the Mediterranean. The endless deserts of the Sahara and Gobi. The vast expanse of Steppe and Prairie of the Northern Continents. The beautiful colours of the Temperate Forests. The endless expanse of the Canadian Boreal Forest and Russian Taiga. The empty Arctic Tundra and Antarctic Ice. The myriad of Wetlands and Highlands found across the globe.
