controlled burns clear brush on the forest floor to make way for saplings to grow. They also assist in replenishing nutrients to the soil. Wildfires can be bad in the sense that they can kill animals if they have not relocated.
Explanation: The reason why controlled fires are good is because for example, the forest wild fires are not good because we need trees to survive, they give us oxygen to breath. So when controlled fires are being taken care of, there are less fires we need to worry about :)
