Ponder a thick layer of insect life that encompasses our planet. Not limited to flying insects, or visible from the ground, a study conducted in Great Britain estimated that as many as 3 billion insects passed over your head in summer. In warmer climates closer to the equator, double that number. Special instruments to collect bugs from an airplane, recorded a single termite, alive, at 19,000 feet. Some fly, some are carried by the wind, most are alive and kicking around 1000 feet.
