Wood is a natural material obtained from trees. It is widely used for construction, furniture, tools, paper, and fuel. There are two main types of wood: hardwood (from trees like oak and maple) and softwood (from trees like pine and fir). Wood is valued for its strength, durability, and natural beauty. It is also a renewable resource, making it environmentally friendly when sourced sustainably. Today, wood remains one of the most important and versatile materials used by humans.
