The disarmament deal signed by America and Russia this week means thousands of nuclear weapons will be heading for the scrap heap in the coming years - few will shed a tear for them. But what can you do with these unloved massive chunks of metal and electronics?

On this week's One Planet we try to find out how much of a nuclear weapon can be recycled and reused. We meet nuclear physicist Frank Barnaby, one of the few people left to have witnessed an atomic bomb being detonated, and ask him how these missiles might go on to enjoy a second life.

Also in the show we head to Nairobi to investigate how easy it is to get rid of electronic waste in Kenya's capital city. Plus we seek out the urban farmers of New York City - there's plenty of chickens, bee hives and cabbage patches among the skyscrapers if you know where to look.

As ever, do have a listen and then let us know what you think. You can email the team at Oneplanet@bbc.com, or join in the conversation on our Facebook page. Send us a message, make our day.
