Forest fires are good for forests over the long term. They remove large old trees that are full of rot, dead wood, and parasites. Those old giants aren't using the sun's light and other resources efficiently, but they block too much light for smaller trees in the understory to grow tall enough to compete. A forest fire clears those out, returns the nutrients in them to the soil, and provides a level playing field for smaller trees to grow and compete.

I wouldn't go full Fight Club Project Mayhem, but I'd love something like a cleansing fire that periodically breaks up or disbands all corporations above a certain size.
