Most people use wood in the form of logs or branches. There are two main types of wood based on the tree species. These are called hardwood and softwood. Firewood is a renewable resource because trees can grow back. However, people must be careful not to use it too fast. If we take too much, the local forest cannot grow back quickly enough.

To burn well, wood must be dry. We call dry wood "seasoned." Wood that is still fresh or wet is called "green" wood.

Green wood is hard to burn because it has much more water. In fact, green wood can weigh 70 to 100 percent more than dry wood. The fire must spend energy to boil the water away before it can burn. To help wood dry, people often split it into smaller pieces. This lets more air reach the inside of the wood. You can split wood by hand with a heavy tool called a splitting maul. Some people use big machines to do this job faster.

People have used firewood for most of human history. It was the main way to stay warm and cook food. Before the Industrial Revolution, coal was not used as much as wood. In medieval times, having the right to gather wood was very important. Even in the 1800s, people in America still valued wood highly. A writer named Henry David Thoreau said everyone needs wood to stay warm.

He believed even rich and poor people needed sticks from the forest.

There are many ways to store wood to keep it dry.

Some people build simple piles or tall stacks. A special circular way to stack wood is called a Holz hausen. This "wood house" is about 10 feet wide and 10 feet high. It holds about 6 cords of wood and helps it dry quickly. In the United States, a standard measure of wood is a cord. A full cord is a pile that is 128 cubic feet. This includes the wood, the bark, and the air spaces between the logs.

Using firewood connects us to how people lived long ago. In places like Nigeria, wood is used for many important tasks. It is used to cook food and make charcoal. It is also used in many cultural and religious practices.

We must also be careful when we move firewood. Moving wood long distances can spread pests and diseases to new trees. Burning wood can also cause breathing problems for some people. If we use wood wisely, it can stay a helpful tool for a long time.
