In addition to environmental factors, experts say that in recent years more and more people have been putting themselves at risk by building homes in areas that are prone to wildfires, such as forests or grasslands. Many people are attracted to such places because it costs less to live there than in cities. Others want to be closer to the beauty of nature.
In California, more than half the state—25 million acres—is considered to be under very high or extreme threat from wildfires. That vast area is home to 11 million people—about a quarter of the state’s population. In fact, wildfires were raging in California as this issue went to press.
That’s why preparing for a disaster is so important. For one thing, experts say, many at-risk towns need more-efficient evacuation routes and better alert systems.
In Paradise, for example, only 6,200 of the town’s 27,000 residents—less than 25 percent—received official warnings of the advancing fire. Thousands of people hadn’t signed up for the alerts, and many of those who had signed up never received them.
Officials also encourage residents to build their homes and fences using concrete, stone, or brick. Those materials are less likely to burn than wood. They also suggest planting only certain types of vegetation that won’t easily dry out. In addition, gutters, porches, and yards should be kept clear of leaves and branches that may catch fire, they say.
Such measures may sound simple, but they can be expensive. Some people, especially the elderly, don’t have the physical ability to regularly clear brush from their yards—or enough money to pay someone to do it for them. Others can’t afford cell phones or internet access to get early warnings, or cars to flee town.
