The past few decades have seen the emergence of megacities--that is, the merging of several metropolitan areas into megapolitan urban forms. This has occurred in the eastern United States, in parts of Europe, and in several other locations worldwide. Many more megacities may now be emerging; for example, some contend that an urban triangle (a new urban form) is developing in Texas between Dallas, Houston and San Antonio. The Texas Triangle (which includes the Dallas/Fort Worth, Houston, Austin and San Antonio areas) is expected to double in population over the next 25 years; by 2030, the 57,000-square mile area will be home to more than 14 million people. Nearly 50,000 new teachers will be needed to educate the 718,000 new students in the area. Truck and rail freight traffic is expected to increase by 60 percent, and air traffic will rise by 40 percent. All this will take place in an area with some of the best farmland in the nation; one of the most extensive and fragile aquifer recharge areas, an area already subject to special protection; the protected habitats of numerous endangered species; and areas that are frequently subject to tornadoes, hurricanes and subsidence. Yet to date, no one has studied this growth as a coherent whole, nor have any design strategies been developed to make the growth more sustainable and minimize its damage to the environment.

Dr. Bright - I enjoy your posts you should keep on updating your blog with rants, and issues because it is nice to hear your opinions on planning topics. It would be nice to see some controversial topics discussed. Have a great summer.
