I hate them. I hate them. I hate them.
I'm not talking about the re-useable ones. My hate is directed at the one-time use bottles which apparently require the user to discard wherever he or she happens to be at the time without taking the time to look for a trash container. Wherever I go outdoors these are the overwhelming main source of litter. I heard that San Francisco has banned them, and good for those citizens if that report is correct. I hope everywhere else bans them too.
