destroying the natural world on which
we depend for future life.

OPT's July 2009 YouGov poll shows that 51 per cent of the public thinks the ideal population size for the UK
is less than 60 million.
Only eight per cent want it to be higher than 60 million.

The Optimum Population Trust
believes that Earth may not be able to support more
than half its present numbers before the end of this century,
and that the UK's long-term sustainable population
level may be lower than 30 million. Research and policy are summarised on this website and
available to all members in the OPT Journal.
In the UK, population is projected to continue rising - from 61 million (mid-2008),
to pass 70 million in 2029 and reach 77 million in 2050. That's more than another two Londons.**
