Total forest area in 2005 was estimated to be around 30% of the planet’s land area, just under 40 million km 2this corresponds to an average of 062 ha (6200 m 2) per capita, though this is unevenly distributedthis estimate was based on data on forest area reported by 228 countries and territories. Tropical rainforest, also spelled tropical rain forest, luxuriant forest found in wet tropical uplands and lowlands around the equatortropical rainforests, which worldwide make up one of earth’s largest biomes (major life zones), are dominated by broad-leaved trees that form a dense upper canopy (layer of foliage) and contain a diverse array of vegetation and other life.
