Why are construction works included among causes of deforestation?

Correct answer: Because land was cleared and timber was used for construction

Direct answer: Option D is correct. Roads, railways, bridges, buildings and other construction require land. Forests may therefore be cleared to create construction sites, and timber may be cut for railway sleepers, beams, houses or other structures. This creates pressure on forest resources. A is wrong because construction does not happen only with water; it needs land, materials, labour and tools. B is wrong because construction normally needs a site and therefore land. C is wrong because construction can directly remove trees and use wood. D correctly connects construction with both clearing land and using timber. Memory cue: construction causes deforestation through two paths: land clearing and wood demand.
