Want clean air? Head to the southern hemisphere
If you're the type who likes to scout out new eco-tourism adventures, you might want to consider a clean air getaway. Where does one find this type of excursion? Well, pretty much anywhere south of the equator. Scientists at Britain's University of York recently discovered a chemical boundary hovering over the equator that serves as a barrier to the North's nasty pollution -- preventing it from dirtying up the southern hemisphere's pristine air.Obviously, since roughly 90% of the world's population resides north of the equator, the air up here is substantially dirtier than down south. Still, scientists hadn't quite discovered why the pollution didn't distribute itself more evenly across the globe -- the north experiences carbon monoxide levels 4 times higher. With the discovery of this chemical boundary, scientists will be able to track pollution levels much more accurately -- and southerners can breathe easy, knowing that a 30-mile wide band of chemicals is protecting their atmosphere.
I wonder if this has anything to do with why Arctic sea ice is facing a collapse while Antarctic ice is still growing?
