The document, prepared for a House of Commons select committee by the Optimum Population Trust (OPT) charity, warns that current projections will force an extraordinary growth in housebuilding.
It also warns that these calculations do not even take into account the current 'fragmentation of households'.
With parts of the country already facing serious water-supply problems, population growth on this scale will make the UK increasingly vulnerable to resource and energy shortages and will increase its contribution to climate change, the report goes on to say.
It also calls for politicians to predict what populations their environments can sustain in the long term, maintaining the best possible quality of life without damaging the environment of other countries.
OPT patron Aubrey Manning, emeritus professor of natural history at the University of Edinburgh, said the UK has a moral obligation to accept some immigration, but needed it like 'a hole in the head'.
'On a global scale, most immigration is a social tragedy, often arising as one result of rapid population growth... which has outstripped the resources to support it.
'A gradual reduction to our population is the only way to secure any quality of life for future human beings,' Manning added.
