Forests

A third of the world's land surface consists of forest-ares of land covered by dense tree cover. Each forest is an ecosystem- a group of animals and plants interacting with the physical environment and one another. More plants and animals live in forest than in any other environment. Forests differ according to the climate-boreal, temperate, or tropical. They help maintain the Earth's natural balance; trees absorb and release gases which regulate the climate.
