When you are having a bonfire or lighting up a charcoalwhy is it necessary to fan it after you put a paper with fire on it. explain?

Fanning a bonfire or charcoal after lighting it helps to increase airflow, which is crucial for combustion. The added oxygen promotes a hotter and more efficient fire, allowing the flames to catch onto the charcoal or larger pieces of wood more effectively. Without sufficient airflow, the fire can smolder or die out, resulting in incomplete combustion and more smoke.
