简介：FOUR-SEASON FORESTSTemperate forests grow between the tropics and the polar regions in both the Northern and Southern Hemispheres. They have four distinct seasons with a well-defined winter. Temperate forests have a moderate climate. They are home to many plant and animal species. Much of the food humans eat is grown in areas where temperate forests have been cleared and farms now exist. If you don’t live in the tropics, chances are a temperate forest once was growing where you are right now. Temperate forests are also where many of our favorite foods first came from.
