With Reference To The Tropical Moist Forest areas Of Brazil, Outline The Main Directions Of development Planning Since 1900, And Assess their Environmental Consequences.

Rainforests play an invaluable role in sustaining life on earth with their existence they aid regulating global climate and the weather cycle, they play an important role also in absorbing carbon dioxide from the atmosphere. they also are a source of food and medicines for many people across the world.

This natural resource covers two percent of the Earths surface(it is thought to have covered much more than this area many years ago) yet houses half of the earths plant and animal species, these species form their own ecosystems within the forests and hold their own particular niche. In total tropical moist forests represent one third of all the earths total areas covered with forest.

Tropical forests are characterised by two distinct features, their location and the amount of rainfall they experience.

There is an area of the world where these forests are more abundant, this is near to the equator between the tropic of Cancer and the tropic of Capricorn. This area has the perfect climatic conditions to produce these forests. The amount of rainfall the area has, has to be nowhere less than 80inches per year . The temperature of the forest is also an important factor in controlling the conditions of these areas this needs to remain constant at around 75 degrees Fahrenheit and essentially needs to remain frost free. This hot, moist, humid atmosphere has been likened to a laboratory hot house and its abundance and richness of plants and animal species justifies this likeness.

Rainforests are usually made up of several different layers, the emergence which is made up of the tallest trees in the forest can sometimes reach over...
