How can the role of cities and construction works in deforestation be understood?

Correct answer: Demand for timber and land increased for construction

Correct answer: A — demand for timber and land increased for construction. Growing towns, roads, buildings, bridges, and other works required materials and space. Timber was used in many forms of construction, while land was needed for expanding settlements and infrastructure. As the demand for these materials and spaces rose, forests could be cut and cleared. A is correct because it shows both links: construction increased the demand for wood, and urban growth increased the demand for land. B is wrong because cities generally placed pressure on nearby resources rather than fully protecting forests. C is wrong because construction requires materials. D is clearly wrong because cities were not built only in water. The important historical connection is urban or infrastructural growth → demand for timber and land → pressure on forests. Memory cue: buildings need both building material and building space.
