I did say the population was already 70 million. That number is readily available without ChatGPT.
90% of UK land is not developed. 35% is natural. Mountains, hills, lakeland, grassland, moorland. That cannot be touched. 55% is farmland.
All I said was that 1% of under-utilised farmland which is being used to grow food that nobody eats could be reallocated for development. That would be just 330,000 acres to support the housing, education, healthcare, work and day-to-day recreation needs for a 10% rise in population. As I said before, to put it into perspective, we have 700,000 acres of golf courses.
About 12% of UK land, over 7 million acres is in the hands of just 50 owners. The aristocracy owns 30% of all UK land including farmland.
I have yet to see houses, schools, hospitals, roads, railways etc being built by AI. We need fit young people to do that.
We have an extensive skills shortage list which includes construction workers and many other trades and professions. Visa are available for migrant workers who can do these jobs.

I am 70 and retired four years ago. My kind of work is now on the skills shortage list with pay well about the national average. The job can’t be done by AI.
We need economic growth not least to support the needs of an ageing population. If you subscribe to the notion that taxes pay for public spending (which it doesn’t but that’s how most people think about it) how do you generate more taxes? By more people working and more productivity.
The current cost of paying the State Pension alone is £146 billion a year. If it continues to rise by an average of 4% a year for the next 20 years the cost by 2045 will be over 300 billion a year. More than double. The government spends 1.4 trillion a year on everything. Pensions alone will account for one fifth of ALL public spending unless we have growth. The net pensioner population is growing by about 150,000 a year - 750,000 new pensioners, 600,000 pensioners dying. Per capita, the cost of the SP will decrease as, contrary to what some people think, the new State Pension will be cheaper in the long run - no addiional state pensions to pay - but the exponential growth in the number of pensioners will wipe out the saving.
On the question of food, which end do we approach it from? Most people now shop in supermarkets. Supermarkets demand mostly unblemished produce of uniform shapes and sizes. (Some will stock wonky carrots or offer bags of irregular-size apples but not much more.) Supermarkets screw farmers on wholesale prices because customers demand low prices because their household incomes are squeezed by rents and mortgages and child care costs.
Personally, I cut out the supermarket by buying fruit and veg in farm shops and have the occasional organic fruit and veg box delivered if I can’t get there. I don’t eat meat and fish so my food bill is low anyway but I know I am in a minority. I make salads, soups, stews and curries. A £17.75 veg box from Abel and Cole goes a long way. In summer, I also grow easy veg, beans, courgettes and tomatoes and freeze the surplus. It doesn’t take much time space to grow food and cook from fresh but many families are too time poor.
Food security will remain a vicious cycle unless we have a massive paradigm shift.
