This natural resource can be extracted by humans through machines and is used for the production of gasoline and other products. The Middle East is a region known for having the largest number of oil sources, which has caused confrontations between countries, foreign intervention, and great profits for these countries, a sample of these gains are the large buildings and eccentricities that are seen in the Arab Emirates like the city of Dubai.
