The following post is to remind us that our country, Indonesia, is one of the world’s largest tropical rainforests that has an important role in keeping our earth survival. Tropical rainforests, also known as ‘the Earth’s lung’, are mainly located in the equatorial zone (between the Tropic of Cancer and Tropic of Capricorn). 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.
To support ‘Save Our Earth’ campaign, www.haarrr.wordpress.com presents an article (written by Denise Tansley @http://www.saveourearth.co.uk) talking about the importance of tropical rainforest. Please take a time to read it!

The Rainforests are the most natural, beautiful, diverse places on this Earth. They are home to many rare birds, plants and animals, contributing around 50 to 80% of the species on this Earth. Today it is termed as. ‘The Lungs of the Earth’ and two thousand years ago, ‘The Gardens of Eden’. Within the last forty years we as a whole have managed to destroy seventy percent of these Ancient Forests.
It takes an average of 300-500 years for a tree to firmly establish its roots with a maximum height for some of the trees reaching 200ft you can easily see why it takes this long and yet minutes to burn. With the size of Wales being destroyed each year for products such as toilet paper, newspaper, writing paper and furniture, the forests are looking more like deserts than the greenery it once was. So where are these forests that we hear so much about, below is a list of them all, many now have been cultivated for land to graze cattle, for roads and of course felled for their timber.
What is the difference between Rainforests and other forests?
Latitude and rainfall distinguish tropical forests from temperate (or moderate climate) forests which are found in warm climates but not too hot to be called tropical. Temperate forests are at ground elevation, mainly in North America, Europe and cooler Australasia. There are many types : deciduous woodland, coniferous woodland, Mediterranean woodland and temperate rainforest.
All tropical rainforests lie between the Tropics of Cancer and Capricorn. They receive more water, being in the monsoon regions. There are many different kinds of rainforest : tropical evergreen, tropical moist deciduous, cloud forest, lowland rainforest and peaty swamp forest.
Rainforests may grow in thin and sterile soil. This is achieved by ample sunlight and water, and nutrients from decaying plant matter. In the warm damp conditions, dead plants rapidly decay and by bacterial or microbial action, the nutrients are released.
The forests are a closed ecosystem where everything is recycled but once these forests are opened, the decaying matter is cleared, the moist conditions disappear and slowly the forest cannot sustain itself.
