Your headline, "Chewing gum is the number one cause of litter" (The Argus, March 31) is untrue.

Gum might be the number one ingredient of litter, but the number one cause is people.

We live among people who don't seem to realise they have to live surrounded by the rubbish they have just discarded in the streets.

The rubbish in Brighton's streets is exceeded only by the rubbish inside those residents' brains.
