the only thing i heard about earth hour was on facebook. i don't think (or know of anyway) that there was any other advertisments for it so i don't think it was probably that effective. But staying on the subject about saving the earth and stuff, i was at the zoo when i was in texas for spring break and i was completely disgusted about how much trash was thrown into their little habitats. i saw a baboon chewing and eating a black 711 cup. i do'nt understand why you would pay 12 bucks to go to the zoo and litter. they specifically have garbage cans all over so this doesn't happen. it just made me sad that people can be so negligent and uncompassionate.
