What is the main benefit of tree plantation?
Answer and explanation
Correct answer: Helping clean the air
The governing concept is the ecological role of trees. During photosynthesis, trees absorb carbon dioxide and release oxygen, while their leaves can intercept dust and some air pollutants. Trees also provide shade, habitat, and other ecosystem benefits. Therefore, option A is the best answer because helping improve air quality is a major benefit of tree plantation. The roots of trees generally hold soil and reduce erosion rather than increase it, so B is incorrect. Healthy vegetation does not reduce atmospheric oxygen as stated in C, and suitable tree planting can support, not reduce, local biodiversity, making D incorrect. Plantation should nevertheless use suitable native species and proper care.
