Why does forest conservation become more important during climate change?

Correct answer: Because forests help environmental balance

The direct answer is A: forests help maintain environmental balance. During climate change, forests become especially important because they absorb carbon dioxide as they grow, store carbon in vegetation and soil, release oxygen, regulate local temperature and humidity, protect soil, support the water cycle, and provide habitats for biodiversity. These functions do not solve climate change alone, but conserving forests helps nature and communities cope with its effects. Option A is correct because environmental balance includes climate regulation, water, soil, and living organisms. Option B is wrong because forests provide habitats and do not remove all animals. Option C is wrong because forests do not only increase pollution; healthy forests generally help filter air and store carbon, although fires or damage can create pollution. Option D is wrong because forests do not simply finish water; they influence infiltration, storage, and the water cycle, even though they also use water. The exam cue is: climate change makes forest protection more urgent, not less.
