But what is the resource that makes Earth that jewel? Is it a raw resource, such as rare elements unavailable elsewhere? Or does life itself - the ability of life to craft chemical bonds atom by atom - combined with vast a biodiversity allowing for the creation of all sorts of novel compounds represent that jewel? That's the question at hand in this thread. Listen to 'Strange Days...
