One thing that interests me about becoming an environment artist is the chance to work in the film industry, not only is it a bigger industry but I think a much more exciting industry. Although the need for environment artists isn't widely known for the films industry but there scenes that require the addition of environment artists as no such place exists in the world.
'Double Negative' visual effects studio came for a visit last academic year and was rather informative of the films industry and what they do within games.
The above video shows the limbo scene in Inception, which Double Negative worked on.
Other industries that modelling can get me into include the television industry, similar to film industry. The music industry is also a possibility as music artists are getting more and more adventurous with their music videos.
Virtual Engineering is another industry that is possible to get in to. Its basically the use of 3D models to simulate and test different scenarios, good example is say a dam, where the design could be tested in a number of different environments to check how it would cope with different scenarios.
