how to protect Envirament ?
Our planet is in trouble! Almost every day we seem to hear of yet another problem affecting the environment - and what a list of problems! - pollution, acid rain, climate change, the destruction of rain forests and other wild habitats, the decline and extinction of thousands of species of animals and plants and so on. Nowadays, most of us know that these threats exist and that humans have caused them. Many of us are very worried about the future of our planet and unless we can find a way of solving the problems we have made then the environment will suffer even more. It all sounds so depressing, but we certainly mustn't despair! Every one of us, whatever age we are can do something to help slow down and reverse some of the damage. We cannot leave the problem-solving entirely to the experts - we all have a responsibility for our environment. We must learn to live in a sustainable way i.e. learn to use our natural resources which include air, freshwater, forests, wildlife, farmland and seas without damaging them. As populations expand and lifestyles change, we must keep the world in a good condition so that future generations will have the same natural resources that we have. Here are just a few examples of the threats to our environment and some ideas to help you to do something about them.

About sinharaja rain forest
Located in south-west Sri Lanka, Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. There is much endemic wildlife, especially birds, but the reserve is also home to over 50% of Sri Lanka's endemic species of mammals and butterflies, as well as many kinds of insects, reptiles and rare amphibians.
Sri Lanka's tropical rain forest, the Sinharaja is a UNESCO World Natural Heritage Site. One of the few virgin forests left in the world. Visitors are required to obtain permits from the Wildlife Department in order to visit this sanctuary. Streams, springs, rivers, waterfalls, leopard, monkeys, butterflies and moths, rare trees, valuable shrubs and medicinal herbs are all found within its green canopy. A trek along prescribed paths would provide nature lovers with a never to be forgotten experience of sights and sounds.
The largest mammal in the forest is the rarely spotted leopard, also infrequently glimpsed are the rusty spotted and wild fishing cats. Sambhur, barking deer and wild boar browse on the forest floor. The more common troops of purple-faced langur monkeys will chatter and move through the trees above you, but you're more likely to hear them than actually see them. There are also rats, shrews, giant squirrels, porcupines, civets, mongooses, venomous snakes, 20 species of birds and 45 species of reptiles.

Sinharaja (vergin rain forest of Sri Lanka)
Sinharaja forest reserve is one of the least disturbed and biologically unique lowland rain forest in Sri lanka. This forest covers an extent of about 11187 hectares from east to west .The length of the forest is about 21km and width from North to South is about 3.7km.It was declared a Man and Biosphere Reserve (MAB) in 1978,as representative of tropical humid evergreen forest Eco system in Sri Lanka and has been recognized by UNESCO as part of it's International Network of Biosphere reserves. It was declared a National wilderness area in 1988 and lately a world heritage site in 1989.It is situated in the southwest lowland wet zone of the country in the districts of Ratnapura, Galle and Matara. The average annual temperature of Sinharaja is 23.6 C. Annual rainfall is more than 2500mm.The rain fall is well distributed during two monsoons, May to July and October to December.
Rainforest Action
- Experts agree that by leaving the rain forests intact and harvesting it's many nuts, fruits, oil-producing plants, and medicinal plants, the rain forest has more economic value than if they were cut down to make grazing land for cattle or for timber.
- The latest statistics show that rain forest land converted to cattle operations yields the land owner $60 per acre and if timber is harvested, the land is worth $400 per acre. However, if these renewable and sustainable resources are harvested, the land will yield the land owner $2,400 per acre.
- If managed properly, the rain forest can provide the world's need for these natural resources on a perpetual basis.
- Promoting the use of these sustainable and renewable sources could stop the destruction of the rain forests. By creating a new source of income harvesting the medicinal plants, fruits nuts, oil and other sustainable resources, the rain forests are more valuable alive than cut and burned.
- Sufficient demand of sustainable and ecologically harvested rain forest products is necessary for preservation efforts to succeed. Purchasing sustainable rain forest products can effect positive change by creating a market for these products while supporting the native people's economy and provides the economic solution and alternative to cutting the forest just for the value of its timber.
The important of rain forests
Hance the rate of water evaporation is high.
As a result there is frequent rain in rain forests.
They are found in south and central America,Africa,
in the Island around Australia and Asia.
The rain forests are important to to human existence
of medicinal plants,food and useful forest products.They maintain about
50% of the plant,animal,bird,reptile and insect species of the world.These
forests help to maintain a regular rainfall They also stand as a buffer against
floods,droughts and erosion .these forests product produce a significant
a most of the world's oxygen.
