On a global scale, forests are shaped by the amount of solar radiation and precipitation, both of which are influenced by latitude. These climatic conditions determine what organisms can survive in an area and have helped shape the evolution of forests for millions of years. Based on latitude, there are three types of forests: boreal, temperate, and tropical. Boreal forests, found farthest north, experience long, cold winters with short growing seasons. Temperate forests, located in the mid-latitudes, have four distinct seasons. Tropical forests, found along the equator, experience high temperatures, long growing seasons, and harbor incredible amounts of biodiversity. Forests support humans on local and regional scales by providing ecosystem services like pollination, climate regulation, and soil conservation. Despite the value of intact forests for human well-being, forests around the world are threatened by human activities, according to the Food and Agriculture Organization of the United Nations (FAO). A forest is an ecosystem dominated by trees. According to the Despite the precise definition laid out by the FAO, there is still controversy over what constitutes a forest. One issue with the organization's interpretation is that it does not differentiate between natural and planted forests.
