Explanation:

why do we need more planted forest = rom our forests we need goods such as timber and non-timber forest products, and ecosystem services, such as wildlife protection, carbon sequestration, and soil and watershed maintenance. By managing them well and applying good practices, planted forests can help achieve these all of these objectives.
