Which of these factors is least likely to explain this "win-win" situation? O Leaving more natural forest increases the biodiversity at the genetic, species, and ecosystems levels in the entire area. O Leaving some of the natural forest is a win for farmers because the forest provides ecosystem services, such as pollination, that farmers rely on for a successful business. O Many of the natural forest species will be able to utilize the coffee plantation habitat. O If the natural forests can provide some valuable ecosystem functions like pest management, the farmers can use fewer pesticides that harm the environment.
