Every second of every day, all over the world, there are more than 100 lightning bolts. That's about ten million lightning bolts in one day! Lightning amazes us, but it canalso frighten us. We have good reason to be afraid of lightning. Every year, about 100people in the United States and Canada die from lightning, and another 300 are injured. Itis strange that of all the people who die from lightning, 84 percent are men. Lightning is themain cause of forest fires; it starts more than 9,000 fires each year
