Yes, but consumption isn't going down. Even if we stabilise at 11 billion people by 2100, which is much too late and arguably already at overshoot mode, consumption will continue rising and increase resource usage, although the population remains about the same. Those 11 billion people won't use the minimum amount of resources needed to sustain themselves (which is a very low quality of life), but use double or even triple than that.
