The Fer-de-lance strikes without warning, and its bite is often fatal to humans.  It is found in South and Central America and various islands of the West Indies, often near sugar plantations.  During the day the snake lies coiled, blending with its surroundings, but it's especially dangerous after sunset, when it wanders in search of prey.  The Fer-de-lance has a thick, reddish brown body.  It has a tapering tail that ends in a hard point.  It has a black stripe that runs from each eye to the neck, and its sides may be bright red.  The snake is usually about  5 ft long, but may grow to more than 7 ft. 

The native people live in harmony with the jungle. They do not hurt the rainforest. But some people do hurt the rainforest to make money. They cut down the trees to make furniture and paper. They burn the forest to clear the land for raising cows. They mine for gold and drill for oil. These people hurt the rainforest only to make money for themselves or their companies. Pretend you are a kid who lives in the rainforest. Who is harming the jungle to make money?

RAINFOREST BIRDS

I sure hope this father survived the war and was able to come home to his little child.

When the siren started to wail I would put on my suit and shoes and make sure my younger brother did the same. Then I would pick up a torch and we would go downstairs ready to go into our air raid shelter. My mother would have already put my grandmother into the shelter and she would have made certain that at least two candles were alight. We had to enter our Anderson shelter (which was in the front garden) by a small doorway, go down four rungs of a small ladder, close the wooden door behind us and pull a blanket over the whole entrance. My father was away in the Royal Navy serving on board H.M.S. Exeter, so I felt I was the man of the house.

There are about 1,000 indigenous tribes in the rainforests of the world.

Those nearest the equator, where the climate is very hot and wet all through the year, are evergreen because the trees can grow all the time and so are always in leaf

Cloud forests are yet another type of rainforest, so-called because they can be found high up mountains, where they are nearly always in cloud. The climate here is very cool but extremely wet.

wood for both timber and wood for making fires; agriculture for both small and large farms; land for poor farmers who don't have anywhere else to live; grazing land for cattle; and road construction

They regulate global climate patterns and help mitigate negative effects of climate change, specifically, global climate warming, (Service 1), and They serve as storages of global biodiversity, specifically plant and animal diversity (Service 2). Those are the two main factors that have been widely put forward as the arguments which are strong enough for us people to try to do our utmost to “save the rain forests” from their continuous destruction

For example, the deforestation rate of the Amazon rain forest (the largest tropical fain forest in the world) during 2005–2006 was the lowest since 1991. (18)

So we should all put as much effort as possible to prevent further destruction of tropical rain forests and save our planet from a potential ecological disaster – we don’t have

The China Conservation and Research Center for the Giant Panda is the most successful center for breeding and caring for endangered giant pandas. The keepers and staff members at the Center take good care of the baby pandas. They care for them from birth until they are old enough to be on their own.©K.Feng/GLOBIO.org The Conservation Center also conducts important research on the surrounding environment. Scientists believe it is important to understand the whole environment and all its species. For example, scientists study the bamboo groves around Wolong. Bamboo is the favorite food

Tropical rainforests have supported humans since ancient times. Although forest life cannot be described as easy, these peoples have built their lives around the surrounding forest and its systems. Consequently, they are a great storehouse of the knowledge about the forest. They know the medicinal properties of plants and understand the value of the forest as an intact ecosystem. As forests fall, these indigenous peoples lose their homes and culture. Conflicts with settlers, who also bring disease and domestic animals, has resulted in the decline of the native population in many areas.

Because there are so many creatures living in the rainforest, there is a great deal of competition for food, sunlight and space. Some animals became very specialised. This means that they adapted to eating a specific plant or animal that few others eat. For example, parrots and toucans eat nuts, and developed big strong beaks to crack open the tough shells. Leafcutter ants climb tall trees and cut small pieces of leaves which they carry back to their nest.The leaf pieces are about 50 times their weight.The ants bury the leaf pieces, and the combination of the leaves and the ants' saliva encourages the growth of a fungus, which is the only food these ants eat. Sometimes there are relationships between animals and plants that benefit both. Some trees depend on animals to spread the seeds of their fruit to distant parts of the forest. Birds and mammals eat the fruits, and travel some distance before the seeds pass through their digestive systems in another part of the forest. One problem with specialisation is that if one species becomes extinct, the other is in danger too unless it can adapt in time. The dodo, a flightless bird of Mauritius, became extinct in 1681. Today there are just 13 calvaria trees left on the island, each over 300 years old, and nearly at the end of their life. Scientists realised that the seeds had to pass through a dodo's digestive system before they could germinate. It seemed that the tree species would also become extinct, but scientists tried domestic turkeys and have successfully managed to germinate some seeds.Many rainforest animals use camouflage to 'disappear' in the rainforest. Stick insects are perfect examples of this. There are some butterflies whose wings look like leaves. Camouflage is of course useful for predators too, so that they can catch prey that hasn't seen them. The Boa Constrictor is an example of a camouflaged predator. The South American three-toed sloth uses camouflage and amazing slowness to escape predators. Green algae grows in the sloth's fur, which helps camouflage it in the forest canopy. Sloths are among the slowest moving animals of all (inside too, as it takes about a month to digest food). They hang from branches in the canopy, and are so still that predators such as jaguars don't see them. Some animals are poisonous, and use bright colors to warn predators to leave them alone. There are several species of brightly colored poison arrow frogs. Native Central and South American tribes used to wipe the ends of their arrows onto the frog's skin to make their arrows deadly
