Water. No, seriously. Water companies or desalinization plants. In 20-30 years, we won't be fighting wars over religion anymore (OK, maybe that is a long shot). We will be fighting over clean water. Population growth will make water scarce sooner rather than later. The problems will begin in India, where the population is skyrocketing and there isn't enough water for their crops. We are already milking the Colorado river for all it's worth. And the Rio Grande is a touchy subject between the U.S. and Mexico.
