Wildfires are uncontrolled (不可控制的) fires. They usually happen in areas where few people live. They are most common in wooded areas in the US, Canada and Australia. They are also known as forest fires or grass fires, or as bushfires in Australia.

Lightning (闪电) strikes and volcanic eruptions (火山爆发) can cause wildfires. However, 90 percent of wildfires are caused by humans, according to the US National Park Service. Dry and hot weather, as well as wind, creates perfect wildfire conditions. They help wildfires spread quickly and last for weeks.

Wildfires can burn at over 900℃ and reach heights of more than 50 meters. Wildfires can move at speeds of up to 23 kilometers an hour, burning everything – trees, brush, homes, even people – in their path.

The fires are also dangerous to animals. In Australia, koalas can’t get enough water from tree leaves because of wildfires. They have to leave their trees and find water somewhere else.

But sometimes, fires can be good for some plants. People can find more of them in the wild after a fire.
