<p>Regarding a minor and careers in Environmental Science, my experience is that that the more “hard” science coursework the better - but each position and individual is different.</p>
<p>I’m not an expert here (just basically familiar) but subfields in Geosciences can be related to Petroleum, Hydrology, Remediation, etc. You may want to search and look into these and other fields to at least gauge a level of interest in each.</p>
<p>Here’s something else to try (if you haven’t already done it): take a look a positions that interest you, then see what education is required.</p>
<p>It sounds like you are set on getting a MS degree, which will open more doors in your future line of work. The cheaper option may be to live at home and finish the Geography degree with a solid academic record while taking the coursework that will best prepare you for your future grad program. A lot of graduate science programs will provide some level of funding to good students.</p>
