Write a short note on forest fire with their causes and effects.
Answers
Answer:
An uncontrolled forest fire can devastate everything in its path, spread for miles, crossing rivers and roads. Each year, between 60,000 and 80,000 forest fires occur, destroying between 3 and 10 million hectares. While forest fires have different impacts on the environment, depending on their size and frequency, the causes are also diverse.
Causes increasingly linked to human activities
A few hundred years ago, forest fires were a natural “activity” caused mostly by rare phenomena, such as a volcanic eruption or an earthquake, that occur in very specific geographical areas. Therefore, it is not them, but lightning, that is the main cause of the departure of forest fires from natural sources. For example, it accounts for about 2% of fires in the Mediterranean zone… and close to 30% in Quebec ! In Spain, 5% of fires are due to natural causes, especially in dry, hot places. In some parts of the country (Aragon, Pyrenean chains, etc.), thunderstorms and lightning, in the absence of rain, are responsible for 25% of forest fire departures.
Answer:
A wildfire, wildland fire or rural fire is an uncontrolled fire in an area of combustible vegetation occurring in rural areas.[1] Depending on the type of vegetation present, a wildfire can also be classified more specifically as a brush fire, bushfire (in Australia), desert fire, forest fire, grass fire, hill fire, peat fire, vegetation fire, or veld fire. Many organizations consider wildfire to mean an unplanned and unwanted fire, while wildland fire is a broader term that includes prescribed fire as well as wildland fire use (WFU; these are also called monitored response fires).
