People often speak of fire as though it were a living creature--It grows, dances, needs oxygen,feeds on whatever it can find, and then dies. And when a forest fire rages out of control, threatening human lives and homes, it must be fought like a "wild animal. " The fight is often desperate, since firefighters' best efforts may be dwarfed by the fury of a large fire. But the fire's own traits can be used
against it.
The heated air above a fire rises in a pillar of smoke and burnt gases, pulling fresh air in from the sides to replace it. Firefighters use this fact when they "fight fire with fire. " They start a fire well in front of the one which they are fighting. Instead of traveling on in front of the huge fire, the smaller fire is pulled back toward it by the updrafts of the larger blaze. As it travels back to meet the large fire, the smaller backfire burns away the fuel that the forest fire needs to survive.
Even when a backfire has been well set, however, the fire may still win the struggle. The wind which the firefighters used to help them may now become their enemy. When the backfire meets the main fire, before both die for lack of fuel, there is tremendous flame, great heat and wild winds. A strong gust may blow the fire into the treetops beyond the area, giving the fire new fuel and a new life.

Japan's 24-hour convenience stores, already struggling with lagging sales and growth, may soon face yet another threat--moves to limit business hours and close the stores late at night. The prefecture of Saitama, which borders Tokyo, may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide emissions.
Kyoto, a former capital, wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry, which fears a withering impact on an already troubled sector also grappling with the. specter of a higher tobacco tax, which could hit overall sales.
"Even if we only operate the stores for 16 hours, we can't stop the refrigerators," said Toshiro Yamaguchi, the president of Seven-Eleven Japan Co. He said such cuts in operating hours wouldreduce each store's profit by 20 percent. "If this happens, our current business model will lose its foundation. "
Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan, their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities," said Masafumi Shoda, an analyst. " But it depends on the store--urban stores do better than others. There are some in the countryside that are inefficient. ''
