Answer to Question 1
The cross border economy is basically developed as a result of where you have a 1st World Country-- the United States, touching a 3rd World CountryMexico, with a common easily crossable border. To attract U.S. companies into a very labor intensive manufacturing industry in Mexico, Mexico agreed for the most part that they could import equipment and materials duty free, and that they could export their products outside Mexico back into the United States. Thus, we saw a large number of manufacturing companies that moved into the area in order to take advantage of low cost labor. The transportation costs could be minimized.
Answer to Question 2
Ogalala Aquifer covers a large section under 7 states. It is a rock strata that is filled with water. Most of this water is geologic water that occurred during the last glacier age, when melting streams from glaciers settled out into the area. Agriculture in the area prior to recognizing the Aquifer was very non-dependable. Most farm families about every 20 years or so found that their agriculture would have trouble making it, so they moved on. When natural gas was discovered here, it produced cheap and easy ways to get the water out of the ground. Farms have continued to prosper from North of Dallas, the Black Prairie, and up to the Dakotas. As a result, there have been more and more wells drilling into the Ogalala Aquifer, and as a result, the natural recharge cannot keep up with demands. This results in the water table plummeting.
