Some joked that the wildfires in the United States have been burning one after another from January to August, with a lot of fire energy.
The Los Angeles Times front page: a single misjudgment caused a small fire to go out of control, triggering a review of firefighting strategies.
Grand Canyon National Park, Arizona - last month, lightning sparked a small fire in the remote northern edge of the Grand Canyon's majestic ponderosa pine forests, and the national park officials saw this as a good thing. Instead of immediately rushing to extinguish the fire as they had done for decades, they followed the theory of modern fire science.
The general view is that the western United States has been shaped by flames that nourish the soil and naturally reduce the supply of dry fuel. The officials set up firebreaks to prevent the fire from spreading to people and the park's historic buildings, then stood aside and let the flames perform their ancient magic.
This strategy initially worked - until it failed. A week later, the wind suddenly increased, and this small, 120-acre controlled burn suddenly turned into a "super fire," becoming the largest fire in the United States so far this year.
As of Saturday, the fire had burned more than 145,000 acres, with 63% of the fire under control. "On Friday, July 11, the fire broke through the defenses we had set up," said a park worker on the front line, still shaken.
