The study from scientists at the University of Roma Tor Vergata in Italy and the University of Rochester in the U.S. argues that a planet\u0027s atmosphere needs to contain at least 18 percent oxygen to facilitate a technological civilization. The reason for this, they say, is a simple one: oxygen is needed for fire.
