A forest is a large area covered chiefly with trees and undergrowth. It serves as a habitat for a variety of wildlife, including mammals, birds, insects, and plants. Forests play a crucial role in maintaining ecological balance by producing oxygen, storing carbon, and regulating the climate. Forests can be classified into different types, such as tropical rainforests, temperate forests, and boreal forests. Each type has unique characteristics, including climate, soil, and biodiversity. They are also important for human activities, providing resources like timber, medicine, and recreational opportunities.
