As a current college student, I can tell you that geography is not a dead subject. My college offers fifteen courses on geography. When you include courses offered in geology (or the science of the earth’s structure, history, etc.), there are a total of fifty-two courses, since geology and geography can influence and affect each other.
We still have an earth to live on. Therefore, there will always be people interested in the way the earth interacts with what is living on it, as the previous answer has stated. As long as there are people interested in this subject, it will not die. After all, as long as there is someone to learn about it, they will find the information they want.
