What if you could build a brick fence in your backyard that would offset a portion of your daily carbon dioxide emissions, such as those produced on your drive home from work? Would you do it?
Ronald Dorn, professor of geography at Arizona State University in Tempe, would. Except the fence he has in mind wouldn’t be just constructed from any old brick. It would be coated with calcium or magnesium and inhabited by a colony of ants.
If this idea sounds bizarre to you, that’s probably because—as Dorn himself would admit—it is. Yet, he says, it is conceivable that people all over the world could one day use their own version of this mineral/ant–based method of CO2 capture to limit the gas in the atmosphere and thereby help control its global heating effects.
