Apparently CO2 isn't all that bad when compared to some other horrible pollutants out there, such as Sulfur Hexafluoride (SF6). A single pound of SF6 does as much damage to the environment as two tons of CO2. Yikes. Used to insulate high voltage equipment, SF6 is odorless, nontoxic, and nonflammable yet still highly damaging to ol' Mother Earth. What to do?
Why, use the new GasFindIR-LW from FLIR Systems. As exciting to environmentalists as that Kaya nipple filter was to perverts, the camera is able to see very small amounts of SF6 in the air as well as 20 other noxious gasses. Once it spots them I'm not sure what you're supposed to do about it, but I guess knowing is half the battle.
