Coca-Cola has released a green version of their popular drink called Coca-Cola Life in Argentina. The new Coke is sweetened with sugar and Stevia, a natural herb which has no calories, but 300 times the sweetness of sugar. It has less calories than normal Coca-Cola at 108 per 600ml bottle. It also comes in a bottle which is made from 30% plant material and is fully recyclable. It is thought this product will eventually be rolled out to the rest of the world.
