  It is well known that there are different global (i.e.
$M_{P}\rightarrow\infty$) limits of N=1 supergravity. We distinguish between
these limits and their relevance to low energy phenomenology. We discuss a)
fermion mass matrices and recently proved theorems in global SUSY b) stability
issues and SUSY breaking d) R-symmetry and a recently derived bound on the
superpotential and e) FI terms in global and local SUSY.
