In Chapters 7 and 8, we examine ongoing developments and controversies regarding legal and illegal immigration and border crossings. We include a photo from several years ago showing our border between Calexico and Mexicali. We also examined troubles with pollution in the New River that crosses the border there.
Regardless of how you think the U.S. and Mexico should be handling these crossings, this article makes it clear that major changes are on tap for our border with Mexico over the next few years; the nature of those changes may be determined by the specific physical and human geography of particular border locations.
