Forest fire as an evil or necessity

The word “fire” evolved from the Greek word “pyra” meaning growing embers. Forest fire may be defined as an unclosed and freely spreading combustion that consumes the natural fuels. It has profound impacts on atmospheric chemistry, biogeochemical cycling and ecosystem structure. It has become intense and more frequent in the last few decades all over the world and is a critical issue in the biosphere–atmosphere interface. It has both the positive and negative impacts on the environment. In India the natural fires are only 5% and rest 95% is caused by human interference. Beneficial impacts; reduce the buildup of fuel, recycle nutrients, reduce competition, allowing existing trees to grow large and remove unpalatable growth remaining from previous seasons when there is limited fires. But when it exceeds its limits it come under the category of forest fire, and may engulf and destroy healthy thick forest cover within no time.
