Fires can be catastrophic in rainforests such as the Amazon, but they don't necessarily spell disaster everywhere — sometimes they help replenish ecosystems. There is even life that needs heat and fire to survive.
I’ve seen it firsthand myself. Compare a patch of land with old growth to one that has been cleansed by fire. Yellowstone is a great example.
It may not work the same in the Amazon. And one has to wonder about the recovery for the millions of acres of fire in the Arctic.
Animals and plants often have a natural capacity for resistance in such fire-dependent ecosystems. The nature of the fires varies, however. In grasslands, savannahs, some forests and wetlands, only a moderately intense ground fire sweeps through, ensuring that the open landscape structure is maintained. Rare but very intense fires are characteristic of bush landscapes or forests. They consume old and diseased trees, create new habitats and ensure an ecological rejuvenation of the tree population.
