  In this paper, we consider the Euler method for backward stochastic Volterra
integral equations. First, we approximate the original equation by a family of
backward stochastic equations (BSDEs, for short).
  Then we solve the BSDEs by the Euler method. Finally, by virtue of the
numerical solutions to BSDEs, we get the numerical solution to original
equation and obtain the global $1/2$ order convergence speed in $L^2$ norm.
