About 4.5 trillion cigarette butts are produced each year world-wide. Because of their size, cigarette butts are easily ignored by people and often go unnoticed. In London more than 78% of them are discarded on pavements and streets which can caused more harmful to the environment than plastic bags. Cigarette butts have become one of the main problems affecting the environmental sanitation of London. The cleaning bill for disposing of discarded butts runs into millions of pounds each year. So we need people “see” the cigarette butts and let them realise that by not disposing of their butts they are adding to the pollution of the city. Proposition: Bin your butts.
