B.S. in Geographic Information Systems or Biology?

I'm taking my first biology cl this semester and there's an insane amount of coursework I have to do. After checking online, I saw that the average salary for a biologist with a B.S. is about $30,000/ yr; I thought for sure it would be more. I don't even find the cl that interesting. I am thinking about changing my major to Geographic Information Systems. Is the pay any better? With emerging technology, how would the job outlook be in the future?
