It is a threat to the quality of life, country's economy and future development. The current rate of deforestation is estimated to be more than 10 million ha/year. If this rate continues, it is feared that the remaining tropical forest may dissappear within a century. > Causes of deforestation : The main causes are as follows- O Explosion of human population : Due to over population of human beings, requirement of timber, fuel, paper, wood etc. has increased. Man has cleared large areas of forests for agriculture, housing, facto- ries, roads and railway tracks. Construction of roads along the mountains which cover nearly 30,000 km in ecologically fragile area is another cause of forest degradation.
