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.
