The phenomenon that forests can purify the air and regulate the climate mainly shows that () A. Plants can adapt to the environment B. Plants can influence the environment C. The environment can influence. Environmental factors will affect the life of plants, such as light, temperature, rainfall, soil type and other factors. For example, in tropical areas, with strong light, high temperature and good moisture, the leaves of plants are large, while in cold high latitudes, the leaves of plants are small. In tropical areas, plants are evergreen, while in temperate areas, most plants are deciduous; The influence of plants on the environment is that plants change the surrounding environment through their own actions. For example, in tropical and subtropical regions, plants grow rapidly and have a great demand for minerals. Therefore, plants secrete organic acids from roots to increase the supply of P and Ca, resulting in low soil pH and acidity. On the contrary, in temperate regions, soil pH is neutral or alkaline. The content of organic matter in forest is high, and these organic matters have strong affinity with water. Therefore, it can increase rainfall, reduce the formation of debris flow and improve the microclimate in this area. Therefore, forests can purify the air and adjust the impact of climate phenomena on the environment, so option B is correct.

So choose: B.
