amazing and beautiful.

rainforest
The lovely bird that all day sings
The parrot with its colourful crest
With all the things the forest brings
We need to take good care
Because all these special things
Can’t be found just anywhere
So let’s look after the rainforest
And give it our protection
Then it’ll be there for all the rest
Of our future generations.

reason it is called a "rain" forest is because of the high amount of rainfall it gets per year. The climate of a rain forest is very hot and humid so the animals and plants that exist there must learn to adapt to this climate. Rainforests are very dense, warm, wet forests. They can be found in hot and humid regions near the Equator. The most famous rainforest is the Amazon but there are also rainforests in Australia, Indonesia, Africa and some parts of the USA. These incredible places cover only 6 %of the Earth's surface but yet they contain MORE THAN 1/2 of the world's plant and animal species!

areas have been cleared for cattle ranching and for sugar cane plantations.
Like other major rainforests, the jungles and mangrove swamps of Central America contain many plants and animals found nowhere else. Central America is famous for its large number of tropical birds, including many kinds of parrots.

forest covers the basin of the Amazon, the world's second longest river.

The Amazon is home to the greatest variety of plants and animals on Earth. A 1/5 of all the world's plants and birds and about 1/10 of all mammal species are found there.

east, the large island of Madagascar was once intensively forested, but now much of it is gone.

Cloud Rainforest in Africa

Africa contains areas of high cloud forest, mangrove swamps and flooded forests. The island of Madagascar is home to many unique plants and animals not found anywhere else.

the west to Malaysia and the islands of Java and Borneo in the east. Bangladesh has the largest area of mangrove forests in the world.

In Southeast Asia the climate is hot and humid all year round. In the mainland Asia it has a subtropical climate with torrential monsoon rains followed by a drier period.

the island of New Guinea formed part of a great forested southern continent, isolated from the rest of the world. Today these countries contain many different species of animal that occur nowhere else.

Undergrowth in Australia's tropical forests is dense and lush. The forests lie in the path of wet winds blowing in from the Pacific.

because they produce most of the Earth’s oxygen. Rainforests basically have four layers .

for light and food has lead to evolution of plants which live on the branches of other plants, or even strangle large trees to fight for survival.

twigs, and foliage. Many species of animals run, flutter, hop, and climb in the undergrowth. Most of these animals live on insects and fruit, although a few are carnivorous. They tend to communicate more by sound than by sight in this dense forest strata.
Contrary to popular belief, the rainforest floor is not impassable. The ground surface is bare, except for a thin layer of humus and fallen leaves. The animals inhabiting this strata, such as rhinoceroses, chimpanzees, gorillas, elephants, deer, leopards, and bears, are adapted to walking and climbing short distances. Below the soil surface, burrowing animals, such as armadillos and caecilians, are found, as are microorganisms that help decompose and free much of the organic litter accumulated by other plants and animals from all strata.
The climate of the ground layer is unusually stable. The upper stories of tree canopies and the lower branches filter sunlight and heat radiation, as well as reduce wind speeds, so that the temperatures remain fairly even throughout the day and night.

a part of a forest between the forest floor and the canopy where small plants such as herbs ,shrubs and fungi grow. It is filled with small trees, lianas, and epiphytes, such as orchids, bromeliads, and ferns. Some of these are parasitic, strangling their host’s trunks; others use the trees simply for support.

their branches. Most of the herbaceous food for animals is found among the leaves and branches of the canopy, where a variety of animals have developed swinging, climbing, gliding, and leaping movements to seek food and escape predators. Monkeys, flying squirrels, and sharp-clawed woodpeckers are some of the animals that inhabit the treetops. They rarely need to come down to ground level.

. The highest plant layer, or tree canopy, extends to heights between 30 and 50 metres . Most of the trees are dicotyledons, with thick leathery leaves and shallow root systems. The nutritive, food-gathering roots are usually no more than a few centimetres deep. Rain falling on the forests drips down from the leaves and trickles down tree trunks to the ground, although a great deal of water is lost to leaf transpiration

in our own homes! We eat several foods from the rainforest and many medicines are made from ingredients found only in these areas.

of the common products we know of include:


chocolate
sugar
cinnamon
rubber
medicine
pineapples

in tropical rainforests. In fact, scientists believe that many have not yet been discovered and named. The rainforest is home to more than half of the world's animals. Colorful and unusual animals dwell in all four layers of the forest. All types of creatures are represented, from tiny insects to large mammals.

and beautiful flowers grow in the rainforests.

live in the rain forests. Did you know that there are about 50,000,000 tribal people living in world's rainforests? These people depend on the forests for their food and shelter. As we cut more and more trees and destroy more and more of the forests, we are also killing people. Many native tribes have been exterminated already because their governments failed to protect them from logging companies, the mining companies and the slash and burn farmers.
Here is some more information about three of the larger and more well-known tribes:
The Pygmies, the Huli , the Yanomami.

Africa. Traditionally they live by hunting and gathering food.

in the remote highland forests of Papua New Guniea. They live by hunting, gathering plants and growing crops. Men and women live seperately, in large group houses. The men decorate their bodies with colored clay and wear elaborate headdresses for ceremonies.

America is the Yanomami. Their village life is centered around the yano, or communal house. The yano is a large, circular building constructed of vine and leaf thatch, which has a living space in the middle.

of 6000 acres every hour (this is about 4000 football fields per hour). When these forests are cut down, the plants and animals that live in the forests are destroyed, and some species are at risk of being made extinct. We need the rain forests to produce oxygen and clean the atmosphere to help us breathe. We also know that the earth's climate can be affected, as well as the water cycle. Rainforests also provide us with many valuable medicinal plants, and may be a source of a cure from some deadly diseases.logging trucks carry away trees that have been cut down.
Forests can be managed effectively without endangering rare species of plants and animals and without risking global environmental damage. Companies that harvest timber should not be allowed to "clear cut" large areas of forest and should be required to plant new trees after they cut old trees down. Governments should create large parks and reserves where hunting and logging are not allowed. As a world community, we must be careful not to destroy the resources that people will need in the future.
