In my theory, I believe that when the oil runs out of the Earth, it would make a big impact for all of us. The heat core becomes smaller and smaller in every couple of years later because we extract the oil everyday for years. The heat becomes less and less that makes our ground lose the heat for the plants' extinction. The ground would become dry out and hard surface. The climate's recycle would come back to freeze temperature that would extinct all of us on Earth, but I am not sure about the water vapors that come from ozone.
I am being to wonder that the oil vaporized in the air that we produce the heat for our house. Does the oil involved in recycle naturally? i.e. An ice cube melted, and there is water. The water vaporized in the air. Then, it goes into the lake, river, and ocean. What about the oil?
I think that the oil is designed for Earth's rotary, and it is not designed for us to extract the oil out of the ground. It created some earthquakes in some countries due default line where there is no left oil in some hidden caves. Maybe, I am silly for me to say that.
I am sorry that this is boring issue, but it looks like that is what the Earth does for us.
