250,000 new houses needed per year

This was the figure quoted on radio 4 this am.

Please note that the population of this country is rising due to immigration – the birth rate for native brits is below sustainable levels (we will be a minority in our country soon enough).

I know (or at least have read) that the Somalian birth rate is 8 on average.

More houses – less space, less green land – more fat kids.

More people, more cars, more shops, more stuff – more roads, more environmental damage.
Is it time to put 2 and 2 together again – and see if we can come up with 4.
