Immigration --> More Building, More Locally-Farmed Food

[gl556tr]

With more building, seemingly on green-field sites that we need to feed more of the population, and net migration >> zero, UK Ltd really ought to take steps to save our farming land and limit building to brown-field sites.
(So-called developers are very happy to grab open fields, there being little or no ground-pollution to deal with.)
Sooner rather than later, we will be forced to rely on home-produced foods, rather than import such products for which competition from the steadily-increasing world population will intensify.
.
A suggestion to ease pressure on growing foods is to use more inner-city sites. Roofs and 'cascading green facades' would bring a two-fold benefit: localised foods and cooling buildings in the Summer.
Any other ideas?

it doesn't help when farmers sell their land to developers, not much one can do about that

There is an abundance of food at the moment - Pie in the Sky!

Stop letting so many immigrants in and then we won't need to keep building more and more homes on green belt land !!

I've never seen the logic of labelling an area a green site if the intent is to build on it. Seems it's only done to a) try and con the public, and b) push the price up. If something is worth saving from building on; then designate it "green" and keep it like that.

As for the immigration/building/farming bit. Unsure what the point was. We should grow crops as needed where appropriate, and limit immigration as much as possible as any net increase in our population is exasperating a situation, not solving it.
