Rainforests are forests characterized by high rainfall, with annual rainfall between 250 and 450 centimetres (98 and 177 in). There are two types of rainforest: tropical rainforest and temperate rainforest. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests.
Around 40% to 75% of all biotic species are indigenous to the rainforests. It has been estimated that there may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests are also responsible for 28% of the world's oxygen turnover, sometimes misnamed oxygen production, processing it through photosynthesis from carbon dioxide and consuming it through respiration.
The Gondwana Rainforests are so-named because the fossil record indicates that when Gondwana existed it was covered by rainforests containing the same kinds of species that are living today. Not all Gondwanan rainforests in Australia are located in the New South Wales- Queensland region; the largest Gondwanan rainforest in Australia is located in Tasmania's Tarkine wilderness. The number of visitors to the Gondwana rainforest reserves in New South Wales and Queensland is about 2 million per year

National geographic - Amazon Forest - BBC wildlife animal documentary The Amazon rainforest (Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica, Amazonía or usually Amazonia; French: Forêt amazonienne; Dutch: Amazoneregenwoud), also known in English as Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 square kilometres (2,700,000 sq mi), of which 5,500,000 square kilometres (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname...
Tropical rainforests cover about 6-7% of the Earth’s land surface and are mainly located in the tropics. That is the regions of the Earth between the tropic of Cancer (23.5° N latitude) and the tropic of Capricorn. (23.5° S latitude) The world’s largest rain forests are the Amazon rain forest of South America, the Congo River Basin in West Africa and the rain forests of South East Asia. There are also smaller rain forests in Central America, Madagascar, the Pacific Islands, Northern Australia, and India. Features of rain forests covered in this video include their location, patterns of rainfall, biodiversity, soils and stratified forests. This video was made in Thailand.

IMAX - 1992 Tropical Rainforest takes you on a 400 million year journey to illustrate the diversity and beauty of life in the forests. Featuring the birds and primates of the forest canopy and insects of the forest floor, Tropical Rainforest also shows the adventure of researchers challenged to understand the forests even as they disappear. From extreme close-ups to tree-top panoramas, the film lets you experience the forest on its own terms, to better understand and appreciate the treasures of this environment. Brilliant!
The tropical rain forests of the world are home to nearly half the animal species on earth - an estimated five million different life forms. More than 100 inches of rainfall each year sustain this lush environment, where some of the most fascinating examples of natural adaptation can be found. Journey to the dense rain forests of Costa Rica and watch as leaf-cutting ants carry sections of leaves many times their weight to underground fungus gardens, a basilisk lizard walks on water, and howler monkeys bask in the sun. Fascinating and thought-provoking, this film is an eloquent warning of the natural wonders we stand to lose on a world scale if human encroachment of the world's rain forests continues.
