I am one of your contemporary litter pickers. My 'patch' is a lovely country lane used by many motorists as a rat-run to avoid the busy main road. Our litter louts are car drivers who chuck drinks cans, takeaway detritus, face masks, crisp and sweets packaging and cigarette ends onto the grass verges. How would you police that? These people couldn't care less about the environment and will leave their rubbish where it suits them. Dog walkers can be just as bad leaving poo bags hanging from tree branches. I litter pick for 2 reasons. At 73 and with considerable spinal facet damage following a train crash years ago, it keeps me moving and I like to see our lovely countryside litter free. I don't get cross anymore. I have to accept there are those amongst us who just don't care.
