Then they saw that their local supermarket had started a scheme to encourage people to recycle cans and bottles. For every four cans or bottles that you returned to the recycling centre at the supermarket, the supermarket would give you 1 reward point. What is a reward point? Well, some supermarkets, garages and other shops give their customers reward points every time they buy things at the shop concerned. You can collect these reward points, and when you have enough, you can exchange them for, for example, a weekend break in a country hotel, or a new MP3 player. I have been collecting reward points from my local supermarket for years. Soon I will have enough to get an electric toaster!

　　So, John and Ann decided to collect cans and bottles, and take them to the recycling centre. For three months, they went out every evening, looking for cans and bottles. At first they thought that they might not be able to find enough. But they were amazed by the amount of rubbish that people throw away – in the streets, in their gardens (or other people’s gardens), in the parks and in the countryside. John Till told the newspapers, “There was enough rubbish out there to fly us to the moon and back.” John and Ann spent hours putting cans and bottles into the machines at the recycling centre. Eventually, they found enough cans and bottles, and collected enough rewards points, to pay for their air fare to America, where I am sure they had a wonderful honeymoon, and went to lots of interesting places.

　　Are you thinking to yourself, that’s a nice heart-warming story about two people who wanted to do what they could to help the environment? I am afraid that I do not feel that way, for three reasons. First, as I told you in an earlier podcast, we in England are really bad at recycling. We are better than a few years ago, but many countries in Europe recycle a lot more domestic waste than we do. On the other hand, we are very good at throwing things away and generally making a mess. We throw away newspapers in the street and on the buses; we throw away food packaging and beer cans in the parks, and plastic bags and bottles in the countryside. John and Ann were able to collect all those cans and bottles only because other people had so carelessly thrown them away.

　　Second, the idea that it is good to pay people to recycle things is still very new in Britain. In other countries in Europe, it is normal to return cans or bottles to the supermarket and to get money in return. In Germany and Scandinavia, they have done this for years. But in Britain, we are only starting to experiment with them. John and Ann were lucky. Their local supermarket was one of only a handful of places where they pay you to recycle things.

　　And finally, what did John and Ann do with the rewards points which they got for all those cans and bottles? They bought air tickets to America. Unfortunately, air travel generates large amounts of carbon dioxide, the main gas responsible for climate change. Trying to be green is not easy!
