Special effects in movies add another layer to the movie watching experience. My favorite types of special effects would have to be fake gore and feature changing effects. I believe that Inception is definitely a great example of explosive effects. The effects to that film made you feel as if you were involved in the actual explosions. Jurassic Park is a great example of gore in films. The chunks of human flesh that we saw being ripped off the bodies seemed to real and added that scary factor into the film.
Shortages affect people in a variety of ways. If there is a shortage of food many people can die from starvation. If the is a shortage of water (a drought) many people can not only die but no one will be able to bathe and the animals can suffer from dehydration. On the other hand, a surplus is entirely different.
