Deforestation: Causes and Solutions.

Extracts from this document...

Introduction

Deforestation: Causes and Solutions Deforestation is a major global problem with serious consequences to the planet. These consequences have negative effects on the climate, biodiversity, the atmosphere, and threatens the cultural and physical survival of indigenous peoples. Effects of deforestation are too great to continue destroying the forests. There are many causes for deforestation. The first and most important cause is wood extraction. Wood has always been a primary forest product for human populations and industrial interests. Since wood is an important structural component of any forest, its removal has immediate implications on forest health. Intensive harvests can lead to severe degradation, even beyond a forests capacity to recover. When the soil has been stripped of its nutrients, farmers move further into the forests in search of new land. And perhaps the worst culprit of deforestation in the Brazilian Amazon is cattle ranching. 38% of deforestation in the Amazon wasdue to large scale cattle ranching. Mining for valuable resources also plays a major role. Deforestation has many devastating effects. It affects climate significantly, in part because the forest plays a major role in the water cycle, recycling rain back into the clouds as it receives rainfall. As a result, when the land is cleared, flooding and drought become serious problems, as rainwater travels quickly through the ground without the forest to regulate it. ...read more.

Satellite photos are used to monitor the rate of deforestation and to spot illegal logging. Sustainable ways of using the forest are being encouraged. Many rainforest products such as fruit and nuts can be harvested without damaging the forest. In places, selective felling is possible. Valuable trees are removed without damaging the surrounding areas. Deforestation: Cattle Ranching I have carried out a report about cattle ranching. I will try and answer the following questions: * Is Cattle Ranching A Major Cause of Deforestation? * How Does Cattle Ranching Effect Deforestation? Cattle ranching is a major cause of deforestation. Forests in the tropics are commonly cut and burned so more cattle can graze. Every year, 5 million acres of rainforest are destroyed in South and Central America to create grazing land for cattle. Many animals and plants are becoming extinct due to this loss of habitat. The popularity of cattle ranching, therefore, has a lot to do with non-profit reasons, such as land ownership and storing value. What farmers and poor inhabitants living in the forests do is the most devastating to our environment. In attempts to settle farmland, the poor become "shifted cultivators" and resort to using slash and burn methods for tree removal. Slashing and burning involves what its name implies, trees are cut down and the remains are burned. ...read more.

Conclusion

What is deforestation & desertification? Deforestation is the removal of trees and natural vegetation from areas of dense forest or jungle. It is done primarily to obtain space that is essential for agriculture, fuel and building. However, there are many environmental issues that have derived solely from this mass wood extraction. Wood has always been a primary forest product for human populations and industrial interests. Since wood is an important structural component of any forest, its removal has immediate implications on forest health. Intensive harvests can lead to severe degradation, even beyond a forests capacity to recover. When the soil has been stripped of its nutrients, farmers move further into the forests in search of new land. As forests are destroyed in this way, habitiats are removed for the animals living in them, therfore the biodiversity decreases. Forests also hold a big role in the water cycle as it relaeases back the water that falls on them through transpiration into the air. If trees are removed this may reduce the amount of water vapour that returns to the air, and may reduce rainfall either locally or in nearby regions which could inevitibly lead to drought. Trees also intercept the rain , lack of interception means that the water will not be slowed down on its way to the ground. Therefore soil erosion and flooding can occur from rapid surface run-off as a result of saturated soils. ...read more.

    however this makes only a very small proportion of the cliff being weathered. The angle at the base of the cliff suggests that mass movement once took place here and so formed this gentle slope consisting of soil and debris, on which has grown vegetation like bramble bushes, grasses, plants and other low shrubbery which can withstand salty conditions.

    It is also able to withstand the other harsh conditions on the younger dunes. These harsh conditions would include very little shelter, so the marram grass would be constantly hit by sand that is blown by the wind. The marram grass is well adapted to deal with this though -

  2. Discuss the biological effects of deforestation with consideration towards preventative strategies.

    Forests store large amounts of carbon that are released when trees are cut or burned. It is projected that deforestation and the burning of biomass will be responsible for fifteen percent of the greenhouse effect between 1990 and 2025. This biological effect of the greenhouse effect will differ in different countries.
