As we all know, oil is becoming more and more important in the modern society in which we live.  In fact, oil appears to have become the a part of life of industry.

Without oil, cars, buses, and all other forms of transport would no longer be able to move.  All the machines in the factories would grind to a halt.  Besides being unable to travel, workers would have no jobs.  Social problems would rapidly increase. The electricity we use could no longer be produced and so we would live in the dark.

In a word, without oil the world would stop moving.  Our life would be miserable indeed.
