Monster Giant Dragonflies Coming To Kill Us

“As you become a larger insect, more of your body is taken up by tracheal tubes. Eventually you reach a limit to how big you can be. The more oxygen that is available, the smaller that system needs to be and the bigger you can grow.”
 — I’m a little offended by Arizona State University paleobiologist John VandenBrooks’ use of the second person here. But I’m much more concerned about the fact that he and his team of scientists have been breeding giant dragonflies in oxygen-rich apocalypse chambers. 50 percent more oxygen = 15 percent larger dragonflies. So you figure if a normal dragonfly can sew a human mouth shut so we starve to death, these new ones ought to be able to bite off our arms and stitch them onto our foreheads.
