A new photo atlas released by the United Nations Environment Program illustrates, in no uncertain terms, humanity’s impact on the planet. We’re talking 300-some pages of salacious satellite images documenting rampant deforestation, retreating glaciers, and massive urban sprawl (a la the images of Las Vegas, Nev., at left, in 1973 and 2000 respectively) in before-and-after photo spreads that put even the most trashy of gossip rags to shame. Sadly, however, I fear more people will see the aforementioned mags than this atlas. Plus, everyone knows before-and-after pics are always doctored. Nice try, U.N.
