In this paper we focus on the global-in-time existence and the point-wise estimates of solutions to the initial value problem for the semi- linear dissipative wave equation in multi-dimensions. By using the method of Green function combined with the energy estimates, we obtain the point-wise decay estimates of solutions to the problem.
