Forestry is the science and practice of planting, managing, and caring for forests. The document discusses the history and importance of forestry, particularly in Pakistan. It notes that the first large man-made plantation in Pakistan was established in 1864 called Changa Manga. More recently, the Billion Tree Tsunami project was launched in 2014 in Khyber Pakhtunkhwa. Forestry provides many advantages such as protecting biodiversity, watersheds, habitats and helping control climate and air quality. However, deforestation threatens these benefits as forests are removed for timber, fuel or agriculture. The document concludes by suggesting actions individuals can take to support reforestation and environmentally sustainable practices.
