Wildfires Across the Globe 🔥🌍

Flames, Forests, and the Human Cost

---

🌲 What Are Wildfires?

• Wildfires are uncontrolled fires in forests, grasslands, or shrublands that spread rapidly due to dry conditions, heat, wind, and human activity.

• Causes:

  1. Natural: lightning strikes, volcanic activity.

  2. Human: deforestation, arson, discarded cigarettes, uncontrolled agricultural burning.

• Global warming has intensified fire seasons, making them longer and more destructive.
