What is any good film without effects. We all love big bangs and explosions.We all love when tension is built by things like music and lighting. And what would any B grade movie be without CGI. All of these bring films together from simple shots to the masterpieces we can see on the big screen today. Examples of films with lots of effects include "The day after tomorrow" and the "Terminator" series. What a lot of people don't think about when they see green screen explosions and CGI is that the explosion must have occured at some point in real life for either the programmer to have seen (in real life or on the TV) or to have been recorded for later use. Now the ingredients for an explosion have a direct relation to geography. Chemicals that make the explosion go "boom" so to speak and look amazing almost all come directly from the ground. Oil makes smoke and gasoline or petrol make the fireball. Granted sometimes the chemicals needed for certain explosions need to be extracted in a lab. But everything comes back to geography. A less direct connection is the computers were made from plastic which was made from crude oil etc.
