Double majoring in biology and environmental science strikes me as overkill. I think you’re much better off focusing on one (biology is probably more relevant) and taking relevant courses in the other. You don’t need to concentrate in marine biology, though given your interests, I do recommend looking for a good track in ecology or organismal biology within biology programs. </p>
<p>If you decide to pick up a second major, I recommend something useful that complements marine science and wildlife biology. Examples are public policy, statistics, and geography (including GIS).</p>
<p>You don’t need to major in photography to do it professionally, though I suppose it may help. It’s really your skills that matter. I’ve done a lot of photography for research projects, and I have only had a couple of classes and some on-site training.</p>
