It is more like a Stag Hunt than a Prisoner's Dilemma, because past a certain point if the risks are real, defection can cause catastrophic outcomes for all players including the defecting one. On the other hand, cooperation could lead to positive outcomes (abundance) for all. So cooperation is a possible equilibrium here.
