Natural fire starters are materials that ignite easily and can help start a fire without the need for synthetic products. Common examples include dry leaves, pine needles, and small twigs. These materials are often found in nature and can be collected for use in campfires or fireplaces. Another effective natural fire starter is cotton balls soaked in petroleum jelly. They burn slowly and provide a reliable flame, making them ideal for outdoor activities. Using natural fire starters is an eco-friendly way to enjoy a fire while minimizing the impact on the environment.
