Clear-cutting of forests: a. Removes the carbon tied up in the vegetation b. Increases the rate of erosion c. Causes the depletion of soil nutrients d. All of the options are correct e. None of the options are correct

d. All of the options are correct

Explanation:

The clear cutting of forests refers to the removal of all the native vegetation of a forest, which remains without any vegetation cover and with the soil completely unprotected. This type of activity is very disadvantageous for the environment because it promotes soil erosion, decreases the absorption capacity of carbon dioxide, causes depletion of soil nutrients and removes all carbon trapped in the vegetation.
