In a bid to save Mother Earth from our lack of ability to use a bloomin' bin, London have now decided to give people an incentive to not just drop their cigarette buts on the floor - and it involves football!
The project started by Hubbub has urged smokers to put their finished ciggies in either the Messi or Ronaldo side to help clean the streets and answer one of life's great questions.
And it seems the smokers of London have spoken... for them it's all about Real Madrid ace Ronaldo!
As you can see, Ronaldo's side is thumping Messi at the moment, but we reckon it won't be long before die-hard Messi or Ronaldo fans will be buying a 200 pack of Lambert & Butler to help make their vote count.
So this project has cleaned the streets and helped to answer one of the biggest debates of this century – fantastic!
