Question

Clearcutting is a controversial practice that is widely applied in forests managed for wood production in many parts of the world. Many of the ecological impacts commonly ascribed to clearcutting, in fact, result from other stages of the wood-production process. All but which of the practices listed below cause the negative ecological impacts? A) roading B) thinning C) slash burning D) control of non-crop vegetation

Answer 1

Answer: Option D

Explanation:

The control of the non-crop vegetation is necessary in order to maintain the fertility of the soil.

The non crop vegetation should be cut in order to maintain the availability of the nutrients, water for the crop vegetation.

Example: The plant named eucalyptus has its roots deep inside the ground. So there is no other plant grown along with this plant because it will not get enough water for its growth.

Likewise the non crop vegetation should be stopped from growing to maintain the ecological balance.
