I have adeep interest in evironmental studies, astrophysics, and, aeronautics. So, I was wondering where I could be heading to with such a crazy combination of subjects. Is there any industry which may use all three? Which university should I go to, to be able to study all of these together. I know the combo is crazy, but, this is really what I want. If not, what other emerging industries are there, in which I could work (with any degree, not the courses stated above). I want work that is interesting, demanding, and high-paying.
