1 Answer

Answer :

(1) excessive fuel wood collection Explanation: The main causes of total clearance are agriculture and in drier areas, fuelwood collection. The main cause of forest degradation is logging. Mining, industrial development and large dams also have a serious impact. Tourism is becoming a larger threat to the forests. The United Nation’s Food and Agriculture Organisation estimates that ‘1.5 billion of the 2 billion people worldwide who rely on fuelwood for cooking and heating are overcutting forests’. This problem is worst in drier regions of the tropics.
