Final answer:
Human causes, other than arson, account for a significant number of wildfires started and acres burned. Understanding the impact of human activities on fire activity is crucial for fire management and prevention.
Step-by-step explanation:
Human causes, other than arson, accounted for a significant number of the wildland fires started and acres burned during those fires. Factors such as accidental ignition, carelessness, and human activities that disturb fire regimes can contribute to the likelihood of wildfires.
For example, the expansion of humans throughout the world has significantly changed the pattern of landscape burning, either intentionally or accidentally. Human usage of fire has a profound effect on fire activity, disrupting natural fire regimes.
Understanding the impact of human causes on wildfires is crucial for managing and preventing future fires.
