Geography Essay: Introduction

Rainforests are known for their distinctive features and natural beauty, and are

among the richest inhabitants in the world. They contain several different

species of animals and provide an essential home for wildlife. Many different

rainforests that are located in Australia are found in the northern region. It

is heavily populated between Townsville and Cook Town. These unspoiled

creations of Mother Nature have already been completely destroyed, along with

Their animal life. In fact very few rainforests are left in Australia and are under

great threat. Numerous numbers of Rainforests have been converted into

farmland, pasture or simply wasteland. There is little questioning about the

survival of rainforests in the future.

Why do our forests continue to be destroyed?

Rainforests all over Australia has been descending at a rapidly low pace.

These problems have arisen mainly due to human activity. The influence

of humankind has played a major factor in the role of deforestation.

Modern machinery is another example for which our rainforests are

being cut down. Millions of hectares every year of agriculture have

previously been demolished, and every half an hour an animal specie becomes

extinct. Human activity is not the only problem in regards to the destruction

of forests. Most people believe that rainforests stand in the way of progress.

They are also destroy agriculture so that the ground can be mined for

precious minerals. Rainforests are said to be inconvenient obstacles. They re

simply removed from nature mainly due to lack of space for pasture etc. More

reasons to why people continue to cut down rainforests, is in addition to timber.

Timber is means of paper and is valuable resource in most countries. Mahogany

and teak has been known to have high priceless values.

Over the past years there has been tremendous change in the cutting down of

trees. Heavy plant and machinery like bulldozers and cranes can clear large

amounts of our forests in a third less time then it takes men with axes. This

modern technology has boosted the rate of deforestation and will continue to

do so.

The consequences of deforestation;

The removal of forests does not always provide a suitable land for growing

crops. When agriculture has been converted into wasteland the ground has

a poor tenacity of nutrients, which means plant life will not be able to prosper

in the environment. After the rainforests have been cleared the land will

only remain fertile for very few years. These extensive land areas can only

grow crops for a short period of time.

Rainforests are accountable for our annual rainfall, since trees absorb enormous

amounts of water. They are also known to leave the atmosphere dense and

moist. This can lead to serious side effects if our forests continue to be destroyed.

Such as drought, flooding and more inclined to soil erosion. When trees are

extracted from our environment the rain can t be absorbed and so it eventually

starts washing away the top layer of soil. Therefore after a rainforest

is destroyed it can never be replaced. Ever so the ecosystem is very fragile

and will be damaged.

Solutions to deforestation;

Current methods have been established to assist with the conservation of

plant and animal life. Many have to do with the preserving and protection of

rainforests. The Government has made more local people aware of what

consequences could eventuate from the destruction of forests. The increase

of carbon dioxide is just another focus point. Due to the lack of nutrients

plant life can not adapt to the region, leaving the crops sustained from annual

growth. However a various type of palm adapts naturally to the soils, which

can help reduce soil erosion. Although soil erosion has a big impact on our

environment logging raisers another question. Luckily a policy called

Selective logging has resolved the devastation of forests. It enables people

to only cut down some trees, not the entire forest. These practical solutions

will all help stabilize deforestation.


At the present rate of destruction, all existence of rainforests will have

disappeared at the end of the century. In the 1950 s there was over 950

million hectares of agriculture, and in the 1970 there declined a

astonishing 200 million hectares. It is estimated by the year 2000

that there will be 500 million hectares persevered. The answer

to why the rainforests are vanishing at a tremendous rate? Lies in the

needs of people.
