The radio documentaries, aired by the BBC World Service, look at what we would be missing if everday mundane things had never existed. This week they look at copper.
"Without copper there'd be no lighting, electrical power for lighting, no radio, no renewable energy systems, no working automobiles, air conditioning or refrigerators, no digital electronics, no computing, no safe drinking water distribution...The last documentary was about Cows and included a UK farm run on Hindu principles and the cow's crucial role in the discovery and development of vaccines, among other things.
"We each have just under half a fingernail of copper in our bodies..."
Brilliant.
In fact, BBC World Service Documentaries wins the RSS Feed of the Month award.
