A collapsing population spells disaster
Mark Craig  cannot have thought this through: an age heavy, collapsing population is not a humanitarian prospect, and unlikely to be good for political stability either. Our schools already have an unprecedented burden of disability and mental ill health [2,3,4] which will surely have significantly contributed to Wellings et al's data [5,6]. This is not to advocate unrestrained population growth, but a sustainable population might still be a good idea.
