Almost all rain forests lie at or near the equator. They form an evergreen belt of lush vegetation that encircles the planet. German botanist Andreas F. W. Schimper first coined the term rain forest-in German, Regenwald-in 1898. Tropical rain forests occupy only 6 to 7 percent of the earth's surface. However, they support more than half of the world's plant and animal species (kinds). More kinds of frogs and other amphibians, birds, insects, mammals, and reptiles live in rain forests than in any other area. Scientists believe millions more rain forest species remain undiscovered. The rain forest provides people with many benefits. Its plants produce timber, foods, medicines, and such industrial products as dyes, fibers, gums, oils, and resins. Rain forests help regulate the earth's climate and maintain clean air. The forests' lush, green beauty and rich wildlife offer a special source of enjoyment. In addition, rain forests provide homes to millions of people. Such groups as the Yanomami of South America, the Dayaks of Southeast Asia, and the Pygmies of central Africa have lived in rain forests for centuries. They make their living by hunting, fishing, collecting forest products, and farming. Traditional forest peoples have acquired much knowledge about the rain forest's plants and animals. In spite of these benefits, people cut down thousands of square miles or square kilometers of rain forest each year. This destruction eliminates thousands of species of animals. A number of governments and conservation organizations are working to preserve the rain forests. This article discusses RAIN FOREST (The future of rain forests). Characteristics of rain forests Climate and soil. The temperature in a tropical rain forest varies little. It rarely rises above 95 �F (35 �C) or drops below 64 �F (18 �C). ...read more.

Resins are sticky substances that people use for varnishing and caulking (making objects watertight). Other important plants include the pitcher plants, which feed on animal life, and the rafflesia, the world's largest flower. A single rafflesia may grow more than 3 feet (90 centimeters) wide. Such fruits as bananas, durians, litchis, and mangoes also flourish in Asian rain forests. Some of the best-known rain forest mammals in Asia include elephants, gibbons, orangutans, and tigers. The forests also support hundreds of reptile and amphibian species and thousands of bird and beetle species. Rain forest peoples of Asia include the Penan of Borneo. They rely on rain forest plants and animals for subsistence and rarely farm the land. Another Bornean group, the Lun Dayeh, clear small areas of forest to make rice farms. The T'in people of Thailand and Laos harvest hundreds of wild plant species from the rain forest for food and other purposes. Africa. Africa's tropics have about 810,000 square miles (2.1 million square kilometers) of rain forest. The forested area extends from Congo (Kinshasa) westward to the Atlantic Ocean. Patches of rain forest also occur on the east coast of Madagascar. African rain forests do not house as many plant species as do the forests of South America or Asia. Small areas of African rain forest support from 50 to 100 species of trees. Many of these trees have their fruits dispersed by elephants. A number of valuable woods, including ebony, mahogany, and sipo, flourish in the African tropics. Other well-known plants from the region include oil palms and coffee plants. Diverse animal life characterizes Africa's tropical rain forests. Squirrels and monkeys share the canopy and sub-canopy with other small mammals, including galagos and golden pottos, as well as hundreds of species of birds. The mandrill, a brightly colored relative of the baboon, and the okapi, a horselike relative of the giraffe, roam the forest floor. ...read more.

Conclusion

Increasing public awareness about the plight of rain forests may also aid the struggle to conserve them. Awareness has grown due to greater exposure of rain forest issues in the media, and to an increasing number of tourists who travel to rain forests. Contributor: Charles M. Peters, Ph.D., Kate E.

    Biology- enzyme coursework

    4 star(s)

    Temperature affects enzymes, low temperature causes the enzymes to have little or no kentic energy, causing the molecules to move slower resulting in less collision and a low rate of reaction. Increasing the temperature increases the kinetic energy of the enzyme and substrate molecules so that they move faster and are more likely to collide.
