The ultimate fate of life in a universe with accelerated expansion
is considered. Previous work by Krauss and Starkman showed that
life cannot go on indefinitely in a universe dominated by a
cosmological constant. In this paper we consider instead other
models of acceleration (including quintessence and Cardassian
expansion). We find that it is possible in these cosmologies for
life to persist indefinitely. As an example we study potentials of
the form $V \propto \phi^n$ and find the requirement $n < -2$.
