Population reduction is impossible. We shall have to accept the solid fact that the world's population is going to rise for at least another forty or fifty years, reach 9 billion souls, and then hopefully start to stabilize.
The answer is NO. Simply because it is absurd to be in favour of something that is absolutely impossible, as proven by the mathematics of population dynamics.
Unless, of course, you want to start killing people off deliberately.
- Which would be a solution that I could never be in favour of.
