We live in a dynamic world, and whether or not changes are "good" for an individual or a group of people depends upon their ability to use them to an advantage. In some parts of the world farmers and ranchers are just as up-to-date in their methods at the close of their productive life as they were at the beginning because nothing has changed. The same was true in America for our grandfathers. It is not true anymore. Now days man's management ability can become "obsolete" three or four times during his productive life if he does not change with the times. We all realize that change is taking place. The rapidity with which it is taking place can best be illustrated by examining the relationship of the number of people supplied with food and fiber by one farm worker in America for years between 1820 and 1967 (Figure 1).
