Steve Martin advocated this way back in the 1970s with his Let's Get Small routine.
I am thinking that rather than reducing the NUMBER of people we should just reduce their SIZE — drastically. Through genetic engineering and selective breeding we could probably reduce the average human size by fifty percent over a few generations.
Think of the energy savings and the abundance of natural resources that could be conserved. A current home could shelter several families, a single cow may feed a village for maonth, and cars would get so much smaller that we could “widen” freeways by merely re-striping them. What a paradise.
Of course, special exemptions will be established for NFL and NBA players.
