1.Deforestation
This method involves cutting down of forests to make space for commercial uses.It is carried out my logging companies that perform it in large scale.This happens extremely fast.In 1850,there was nearly 20million square kilometres of rainforest.By 2005,only 9-12 million square kilometres remain.The effects of deforestation are devastating.When deforestation occurs habitats are destroyed.Plants and animals lose their homes and the ecosystem is damaged.Soil erosion is also a big factor.When trees are cleared, the canopy that protects the soil from rain is exposed.When rain hits the exposed soil,it loses it fertility as the nutrients are washed downwards by the rain(leaching).Thus, deforestation is a very risky way of maximising land use,although its one of the fastest.The top 3 countries with the highest deforestation rate from 1990-2000 are:1.Brazil 2.Indonesia and 3.Sudan.They lost 8,915/5,065/3,702 square miles of forest respectively.
