  We settle a result on generic exactness of SUSY in 3-D, and provide a
mechanism of F-term spontaneous breaking of 3-D SUSY, with a different set of
tools from those used by O'Raifeartaigh in his seminal work on 4-D SUSY. In our
study, we use techniques of projective algebraic geometry so as to deal
successfully with cubic hypersurfaces.
