My background is mainly in multimedia and animation, but I'm interested in going to into graphic design. My impression is that most graphic design work is in advertising. This is a worry for me as I have strong ethical concerns. That is, there are many companies and products that I wouldn't feel comfortable promoting because they have poor ethical score cards. (Environment, human and animal rights etc.) Should I just stay out of the industry, or is it realistic to seek out clients who are in alignment with my values?
