How does using less paper help forest conservation?

Correct answer: It may reduce pressure on trees

Paper is commonly made from plant fibres, especially wood pulp. When people use less paper, reuse sheets, and recycle paper products, the demand for fresh wood can decrease. This may reduce pressure on trees and forests, although paper saving alone cannot solve every conservation problem. It is one practical way to use natural resources more carefully.

The correct choice is C, because using less paper may reduce the amount of wood needed for paper production. The other choices describe effects that do not follow from paper conservation: it does not increase hunting, empty forests, or cause fires. The important chain is simple: less paper demand can mean less wood extraction, which can support forest conservation when combined with recycling and responsible management.
