When I was born (early 1980s) the world population was 4.6 billion. Today it is 7.9 billion. Having the entire world population experience a 171% change over just half a lifetime is not sustainable or healthy. Dont let anyone tell you there isnt a population crisis.
@Rado1 Of course its not linear... I've done tons of research on population growth.. The problem is the non-linearity occurs due to starvation and competition for resources or otherwise making the world hard to survive in reducing the number of kids someone wants to have.
Non linear is the problem, its nonlinearity is directly where the suffering and starving occurs.
