In your opinion, what is a more worthwhile or better/useful major: Geology or Environmental science?

My husband has an environmental science degree and he never worked ONE day in the field, he got a job in the bank and has never looked back, he's an Irish MD in a global bank now and aiming for European Head.. and further afield. I think it doesn't matter what your degree is, having one just proves you can put your head down and work and learn, get a degree in anything you can for now and find your way later..
