The rainforests will receive around 98 to 177 inches of rainfalls or 250 to 450 cm of rainfalls every year. An alternative explanation for this geographic pattern is that in the Southern Hemisphere, especially on islands, there are more refugia—i.e., isolated areas whose climates remained unaltered while those of the surrounding areas changed, enabling archaic life-forms to persist. Tropical rainforests have high levels of biodiversity. Fact 1: Rainforests only cover around 2 percent the total surface area of the Earth and about 6% of the Earth‘s land surface, but about 50 percent of all known species of the plants and animals on the earth live in the rainforest. Only later—during the middle of the Paleogene Period, about 40 million years ago—did cooler, drier climates develop, leading to the development across large areas of other vegetation types. The principal areas of tropical deciduous forest (or monsoon forests) are in India, the Myanmar–Vietnam–southern coastal China region, and eastern Brazil, with smaller areas in South and Central America north of the Equator, the West Indies, southeastern Africa, and northern Australia. You can find tropical rainforests in Central America, South America, Mexico, Asia, Africa, Australia. Regrettably, tropical rainforests and tropical deciduous forests are now being destroyed at a rapid rate in order to provide resources such as timber and to create land that can be used for other purposes, such as cattle grazing (see deforestation).
