Rainforests
Tropical rainforests are forests with tall trees, warm climate, and lots of
rain. In some rainforests it rains more than one inch every day!
Rainforests are found in Africa, Asia, Australia and Central and South America. The largest rainforest in the world is the Amazon rainforest. The Amazon makes up 54 percent of the planet’s rainforests.
Rainforests are important to the global ecosystem. They provide a home to many plants and animals who help stabilize the world's climate, protect against flood, drought, and erosion. They are also a source for medicines and foods.
Sadly, many rainforests are being destroyed. Every year an area of rainforest the size of New Jersey is cut down and destroyed. The plants and animals that used to live in these forests either die or must find a new home.
Humans are the main cause of rainforest destruction or deforestation. Deforestation is another word for when the trees in a forest are cut down and removed.
Between 2004 and 2005, the average annual deforestation rate in the Amazon was 13,900 miles per year. If this continues, the Amazon will be reduced by almost half in the next two decades. This could mean the extinction of many species.
Humans are cutting down rainforests for many reasons, including wood for timber, grazing land for cattle and road construction.
Rainforests are disappearing very quickly. The good news is that there are a lot of people who want to save rainforests. The bad news is saving rainforests is not going to be easy.
There are a few things we can do to help save rainforests. We can help restore damaged ecosystems by planting trees on land where forests have been cut down. We can encourage people to live in a way that doesn't hurt the environment. We can also establish parks to protect rainforests and wildlife and support companies that operate in ways that minimize damage to the environment.

What is a forest?
What is a forest?
Forests are small biomes. They represent a third of the Earth's land. A forest is an area with a high density of trees.
Forests are also referred to as:
a wood
woodland
wold
weald
holt
firth
While humans and animals breathe in oxygen and exhale carbon dioxide, trees take in carbon dioxide and produce oxygen.
What kind of forests are there?
Distinct forest types occur within each of the broad biome groups. According to UNEP there are 26 major types of forests, which reflect climate zones as well as trees types.
These 26 major forest types can be reclassified into 6 broader categories:
temperate needleleaf
temperate broadleaf and mixed
tropical moist
tropical dry
sparse trees and parkland
forest plantations
Do different trees live in different forests?
Trees as well as other organisms change depending on the forest, it's climate and structure.
Trees come in different shapes and sizes. There is an incredible diversity of tree species around the world -- some 60,000 to 70,000 species of trees have been identified! New species are being identified all the time. Different trees live in different forests. You will find Evergreens in Acadia National Park in Maine, Palm Trees in the Rain Forest, and the Boabab in Madagascar.
What are the world's largest trees?
There are many trees that live in the world's many habitats. The largest recorded tree (measured in volume) is named General Sherman, a Giant Sequoia, found in the Sequoia National Forest, CA. The tree is believed to be between 2,300 and 2,700 years old. It is so big that you could drive a car through it!
Are the world's forests in danger?
Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all.
Because we share the world with many other species of plants and animals, we must consider the consequences of our actions. Over the past several decades, increasing human activity has rapidly destroyed or polluted many ecological habitats throughout the world. It is important to preserve all types of biomes as each houses many unique forms of life. However, the continued heavy exploitation of certain biomes, such as the forest, freshwater, and marine, may have more severe implications.
How can I help the forests?
Deforestation represents a great threat to the future of the earth's atmosphere, and the only way this can be avoided is by careful management of this resource. Once a tree is cut down, another should take its place, but there is still too large a number of trees being cut down as opposed to the number of trees being planted.
Pollution is another way we endanger the forests and in turn endanger species. Our governments, companies and all of us need to act more responsibly by maintaining our lands and it's organisms.
As people we can do our best to keep the forests clean and pollution free. This helps us as well as the living breathing plants and animals. Thus we can clean up after ourselves and try not to destroy these natural surroundings when we are enjoying them.

INTERNATIONAL YEAR OF FOREST 2011
What is the Year of the Forest?
The United Nations General Assembly declared 2011 as the International Year of Forests to raise awareness on sustainable management, conservation and sustainable development of all types of forests.. Let's do our part to keep these valuable habitats intact.
That means caring for our land and everything in it's ecosystem. After all, forests are the habitats for creatures and organisms such as plants and trees. They all work together!
Help protect the planet.
