Introduction:
A forest fire is a large, uncontrolled fire that burns in forests, grasslands, or pastures. Forest fires can start due to natural causes or human activities and spread very quickly, burning everything in their path.

Causes of Forest Fires:
1. Natural Causes
- Lightning is one of the main natural causes of forest fires. When lightning strikes dry trees or grass, it can start a fire.
- Extreme Heat and Dryness: In hot and dry conditions, forests become more likely to catch fire easily, especially if there are dry leaves or dead plants around.
2. Man-made Causes
- Human Activities: Sometimes, people accidentally start forest fires. For example, campfires left unattended, burning garbage, or throwing lit cigarettes in the forest can start a fire.
- Deforestation: When trees are cut down and left to dry, they can easily catch fire and spread.
Effects of Forest Fires:
- Destruction of forests
- Loss of wildlife
- Loss of Habitats
- Air pollution
- Climate change
- Soil degradation
- Economic losses
