Did the cultures you studied survive without one? I think you will do just fine, history dictates. You obviously studied anthropology for a reason.

Opportunities will develop when you add to your general background in anthropology some additional skills, like language competency or extensive knowledge of a specific region or experience with either quantitative or qualitative research methods. At the undergraduate level there are more avenues to pursue for jobs/internships in archaeology (e.g., work on digs, internships at museums) and biological anthropology (if you have lab skills) than in cultural anthropology because the latter is so often a solitary undertaking. However, if you forge a solid relationship with a professor who is actively engaged in research you might find opportunities for interview transciptions, library research, or data analysis.

Well, you got some great answers already. And I will agree with everybody else here, yes you can survive with an anthropology degree. A post-graduate degree in the field will of course open more doors for you if you decide to major in it. Also, as far as getting an internship, you may have to organize it yourself. I found mine by traveling in Central America and talking to the people I met there. To give you another example of what you can do with anthropology, here is my story: I got a B.A. in visual arts (minor in anthropology) and a Master in cultural anthropology. I love film and always dreamed of making my own documentaries. More and more health or other development projects are using film and video as a way to implement/communicate/promote. Mixing both disciplines has worked for me just fine. I ended up working for a small NGO, which then got me to work with doctors without frontiers.
