Forest farming, or agroforestry, is a combination of forests and farmland used in agriculture, and it has been practiced for thousands of years. There are numerous positive aspects of this particular farming practice. The most important is the preservation of forests, which plays a key role in fighting climate change. Also, trees prevent soil erosion, enrich the land, and help to conserve different living species. People who are in favor of agroforestry either plant acres of trees on patches of land, or start farming in forests that already exist. For instance, a man named Jono Neiger has created a farm alongside the Connecticut River in Massachusetts called Big River Chestnuts. He planted chestnuts, smaller trees, bushes, elderberries, and he released chickens into the forest. Agroforestry favors biodiversity and is associated with a variety of valuable species that thrive in cooler environments covered in shades, such as the shiitake mushrooms, as well as different medicinal plants. Forest farming protects forests and encourages planting more in order for agricultural engineers to make profits while preserving the environment.
