If you take the appropriate course load to have a focus on some specific discipline (rather than introductory courses of several scientific disciplines), you should research what type of work one can pursue with an undergraduate degree in math, chemistry, biology, earth science, or whatever discipline you decide to pursue.
The people I know of that have science based undergraduate degrees often had to pursue graduate or terminal level degrees to become competitive in their respective areas. This could be very different depending on where you want to go in life. A forest ranger with an earth science based NS&M degree might be fine with an undergraduate degree, but someone working in bioinformatics may need a MS or PhD, for example. I am talking generally here, and hope that someone can correct me if I am mistaken on this.
