I love the BBC’s ‘World Without’ documentaries

TheBBC World Service Documentaries are radio shows that look at what we would be missing if everyday mundane things had never existed. For example, 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…

“We each have just under half a fingernail of copper in our bodies…”

A previous¬†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.
