The American method of litter dispersal is more effective. We don't drop it outside fast-food outlets, we drop it out of moving cars, so that each piece has a chance at finding its own resting place along the hillsides. No asymmetrical piles of crap for us. We create geographic patterns along the freeways and byways of America. Killing two proverbial birds with one large calcified Big Mac. Cheers and good article.
