Great idea your Maj, but sad that she has had to request this. It is the responsibility of each individual to pick up their own litter, but sadly not a lot do. It's the LA's responsibility to empty the bins and keep the streets and pavements etc. clean. I occasionally pick up litter within reason, but sometimes you don't know what it is or what it contains. Yesterday, abandoned in a lift, there was a half filled cooking oil bottle which definitely did not contain oil 
We have an annual beach clean up and marigolds are worn! Always amazes me that folk can bring everything bar the kitchen sink to the beach, but seem incapable of taking any of it home with them - or place the rubbish in the strategically place bins.
