What is a rainforest?
354196
A rainforest is a forested biome with high annual rainfall. Tropical rainforests arise due to the Intertropical Convergence Zone, but temperate rainforests also exist. As well as prodigious rainfall, many rainforests are characterized by a high number of resident species and tremendous biodiversity.

Rainforests must be the only natural thing left that delays human extinction!\n\nAnswerer 1 is also very right! \n\nBut that doesn't mean that his answer is better than mine!

Of course it is. Rainforests are made up of living trees. Trees grow back. Almost all of the Amazon rainforest for example has been cleared for crops sometime in the last 1000 years. It has all regenerated from being totally razed for slash and burn agriculture. It isn't ancient pristine forest.\n\nThe idea that rainforest don't regenerate is a lie told by some conservation groups. Rainforest has evolved to cope with tornadoes, floods and fires and to recover from the devastation those events cause. It regenerates rapidly and perfectly even if it is completely levelled.\n\nThe only problem comes when there are no adjoining areas from which seeds can move to colonise bare spaces.

hey, go to www.Wikipedia.com   type in "Renewable Resources of the Rainforest"  it will give u thousands of things to pick from. Wikipedia is the best for homework and research. Good Luck.

Rain.  Rain. Rain. Rain.  It's a RAIN forest!\n\nThose ghetto types don't like to get wet, so it's name is of Native American origin.  So it's not that "ho"! \n\nHa ha!

Tropical and temperate rain forests have been subjected to heavy logging and agricultural clearance throughout the 20th century and the area covered by rainforests around the world is rapidly shrinking. It is estimated that the rainforest was reduced by about 58,000 km² annually in the 1990s. Rainforests used to cover 14% of the Earth's surface. This percentage is now down to 6% and it is estimated by some that the remaining natural rainforests could disappear within 40 years (mid-21st century). Biologists have estimated that large numbers of species are being driven to extinction, possibly more than 50,000 a year, due to the removal of habitat with destruction of the rain forests. Protection and regeneration of the rainforests is a key goal of many environmental charities and organisations, including EcologyFund and the Nature Conservancy.

Characteristics\nRainforests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 2,000 mm (about 78 inches or 2 meters) and 1700 mm (about 67 inches). The soil can be poor because high rainfall tends to leach out soluble nutrients.\n\nRain forests are home to two-thirds of all the living animal and plant species on the planet. It has been estimated that many hundreds of millions of new species of plants, insects, and microorganisms are still undiscovered and as yet unnamed by science. Tropical rain forests are called the "jewel of the earth", the "Earth's lungs", and the "world's largest pharmacy" because of the large amount of natural medicines discovered there.\n\nDespite the growth of flora in a rainforest, the actual quality of the soil is quite poor. Oxisols, infertile, and deeply weathered, have developed on the ancient Gondwanan shields. Rapid bacterial decay prevents the accumulation of humus. The concentration of iron and aluminium oxides by the laterization process gives the oxisols a bright red color and sometimes produces minable deposits (e.g. bauxite). On younger substrates, especially of volcanic origin, tropical soils may be quite fertile.\n\nhttp://www.answers.com/RAINFOREST

In addition to rainforests--coral reefs. Over-fishing, pollution, and warming are negatively impacting the reefs in many parts of the world.

Tropical rainforests exist because of the unique climatic conditions found in the regions north and south of the Earth�s equator. Continuous heat and humidity allow trees and plants to grow year round, without seasonal interruptions.\n\nRainforests are defined by rainfall.  In fact, they are literally created by it. Weatherwise, they have an average rainfall of 160 to 400 inches with daily temperatures averaging over 80 degrees Fahrenheit and a relative humidity that never falls below 80%.\n\nIn the Amazon basin there are at least 130 days of rain a year and, in many places, up to 250 days. Temperatures change little between daytime averages of 31 degrees Celsius (88 Fahrenheit) and night-time lows of 22 degrees Celsius (72 Fahrenheit).  As a result of these conditions, the tropics are inhabited by thousands of species, trees, plants, animals and insects which all uniquely adapted to the climate.\n\nWhere are tropical rainforests?\n\nTropical rainforests are located around the equator from the Tropic of Cancer in the north, to the Tropic of Capricorn in the south. The largest rainforests are in Brazil (South America), Zaire (Africa) and Indonesia (islands found near the Indian Ocean). Other tropical rainforests lie in Southeast Asia, Hawaii and the Caribbean Islands. The Amazon rainforest in South America is the world's largest, covering an area about two-thirds the size of the continental United States.

Hi Danieller, I have put together all the information on this topic for you, so if you decide to go with it, all the research is done.\n\nThe Amazon Rainforest\n\nHelp with Rainforest School Reports\n\nhttp://www.rain-tree.com/schoolreports.htm\n\nhttp://www.extremescience.com/AmazonRiver.htm\n\nThe Amazon Rainforest\n\nhttp://www.bbc.co.uk/dna/h2g2/A925913\n\nThe Amazon region has a great forest that presents the largest biodiversity of the world.

And it's not just the forest that suffers. Soya farmers often force indigenous peoples off their land before bringing in the bulldozers to clear and then burn the forest. The use of slaves to clear the land has also been reported.\n\nhttp://www.greenpeace.org.uk/forests/forests.cfm?ucidparam=20060307133001&CFID=4989237&CFTOKEN=73924303\n\nAmazon 'stealth' logging revealed\n\nhttp://news.bbc.co.uk/1/hi/world/americas/4362760.stm\n\nDemand for Brazilian beef threatens rainforest\n\nhttp://www.scidev.net/news/index.cfm?fuseaction=readnews&itemid=1314&language=1\n\nAn acre of Brazilian rainforest is destroyed every nine seconds. \nIn Brazil there have been 90 distinct indigenous cultures that have become extinct this century. \n\nhttp://archive.greenpeace.org/comms/cbio/brazil.html\n\nThreats and Solutions\n\nhttp://www.greenpeace.org/usa/campaigns/forests/the-amazon-rainforest/threats-and-solutions\n\nAmazon Photos\n\nhttp://www.leslietaylor.net/gallery/gallery.htm\n\nGood luck.\n\nKevin, Liverpool, England.

Ayahuasca (aya-soul/dead, wasca-vine/rope) or Yage (ya-hey) are native Amazonian names for the jungle vine Banisteriopsis Caapi, and the medicinal tea prepared from it. \n\nThe Banisteriopsis vine is a Malpighiaceous jungle liana found in the tropical regions of Peru, Bolivia, Panama, Brazil, the Orinoco of Venezuela and the Pacific Coast of Colombia/Ecuador. The vine constitutes the common base ingredient of the Ayahuasca tea which is used widely used throughout indigenous Amazonia to enable access to the visionary or mythological world that provides revelation, healing, and ontological security (Dobkin De rios 1972, Grof 1994, Andritsky 1984).
