The lumber industry involves the harvesting, processing, and distribution of wood from trees. This industry plays a crucial role in providing raw materials for construction, furniture, and paper products. Sustainable practices are increasingly important, as they help ensure that forests are managed responsibly and can regenerate over time. Lumber is categorized into softwood and hardwood, depending on the type of tree it comes from. Common softwoods include pine and spruce, while oak and maple are examples of hardwoods. The industry also faces challenges such as deforestation, climate change, and market fluctuations, which can impact supply and demand.
