I'm also amazed that so many aspects of our lives are created from stuff that we extract from Earth instead of building a sustainable and renewable source of it. Oil is used in everything from asphalt that we lay on roads to polymers in medical drugs. Just looking around, so much stuff in our daily lives is made from oil that it's difficult to imagine how the world would look after all of it is moved to a sustainable manufacturing when oil starts to run out or for people living on Mars.
