Wildfires are a thoroughly man-made disaster. Globally, on average, 350 to 450 million hectares （公顷）were burned by wildfires every year. That's about the size of India. Lots of wildfires are intentional. They are often used to clear-cut land for agriculture. But humans are mostly to blame for accidental fires.Causes of accidental fires are various. Firecrackers, campfires or something as common as a car pulling onto dry grass. But the major reason is power line. Trees can blow into power lines or power lines can come down in strong winds. Electrical lines and equipment caused 16 of the big fires that killed 44 people and burned a quarter million acres in Northern California in October 2017 and 15 of those 16 specially to power company PG&E.
How do we solve the problem? The best solution is to bury the power lines underground, but that is a huge project, and no one is jumping at the chance to pay for it. Who is responsible for it, government or private users? It becomes a little confused.
People are thinking of several ways to fight back against wildfires. Bury power lines, build firebreaks into communities, or do more controlled bums. But Mike Flannigan, a wildfire expert at the University of Alberta in Canada, thinks that sometimes we do well to take the humans out of the wild entirely. Every human-caused fire is preventable. If we keep the people out of the forest and wildlands, then there are no human-caused fires. Forest closures work, which is not popular, but it could save a lot of grief at times. In other words, if humans cause most fires, then this is a problem with a solution.
Humans need a bloody nose or two before we change our behavior, and we have had quite a few bloody noses, so it is time to start changing our behavior.
