The correct answer is: C. forty.
Plantation forests produce around 40% of industrial wood. This is a significant amount, and it is important to consider the environmental impact of plantation forests when making decisions about how to manage our forests.
There are a number of factors to consider when evaluating the environmental impact of plantation forests. One important factor is the type of tree that is being planted. Some tree species are more invasive than others, and they can have a negative impact on native ecosystems. Another important factor is the way in which the plantation forest is managed. If the forest is not managed carefully, it can lead to soil erosion, water pollution, and the loss of biodiversity.
Overall, plantation forests can have a positive or negative environmental impact, depending on how they are managed. It is important to carefully consider the environmental impact of plantation forests before making decisions about how to manage our forests.
