There doesn't seem to be enough data to truly say what the ideal amount of time outdoors is.
Outdoor classes used to be pretty common, so being outdoors isn't even necessarily bad for learning maths...

That means UV exposure outdoors is worse now than it used to be.
Unfortunately, it seems nobody measured UV at ground level before we started destroying the ozone layer, but there are barely any historical accounts of serious sunburn before ~1930. Everyone just talks of heat stroke and dehydration rather than actual burning/peeling of the skin.
It isn't about cancer. It is about modern standards of beauty. Sun ages skin. People learned to avoid the sun because of cancer, but they hide in the shade today to keep their skin looking youthful.
We're raising generations of people who aren't even developing basic human abilities like having more than 5 second of attention span, being physically fit or being able to see apparently, the drawbacks are starting to weight a lot imho
I heard my whole life how my generation was going to be useless too. Ruined by arcades and violent tv shows. I am not saying there aren’t going to be drawbacks but “5 second attention span” sounds like the same ole same ole to me.
Are your factoring in a drastic population decrease?
If you flatten out all tall buildings that house XX or XXX apartments you will a lot more space for the city. Which means the cost of rail, trains and a lot of service will increase.
It may be a lot like the suburbs, but with the houses closer and shared green space?
Is the garden meant to provide food for the people living there? If so who is doing the farming? A return to an agrarian society?
I would love to end factory farming, but is not a feasible option to feed as many people as we do today. Which again would be solved be a massiv reduction in the population.
There are 8 billion people on Earth.
So if you gave each family of four a 50x100 foot plot of land (i.e., 5,000 square feet of space), then you could fit eight such plots per acre (with 3,500 square feet to spare for communal space) -- because an acre has 43,560 square feet.
So you would be able to fit 32 people per acre, and since Texas has 171 million acres, you would be able to fit 5.4 billion people in Texas. Since the world has more than 5.4 billion people, we will have to conquer Mexico or Oklahoma.
Long story short, there will be plenty of space left over in Asia.
The worst, closest, time was while at school. The kids were learning writing, Japanese characters. They were sitting at desks, their heads looking straight down onto paper as they learned to create tiny perfect characters. But at the doctor, the kids were given eyeglasses to correct their vision to the 20/20 western standard which itself is largely based on operating vehicles or seeing blackboards in giant lecture halls. So kids with glasses optimized for distance were forcing their eyeballs out of shape to focus on schoolwork literally inches from their face. The finding was that perhaps Japanese eye doctors should prescribe glasses based on what kids actually need (close focus) rather than pretending they all are going to be driving cars and flying planes.
I always thought my good eyesight was from genetics from my father's side--but maybe it was the relatively free-range upbringing that he both experienced--and also paid forward to me--that might have been the deciding factor.
The scale and pace of the transformation is insane
My kids grade schools: 15 min playground time after eating. The 5-6 classes gave 30-60min of homework, each. So it was home, eat, homework, cubscouts/etc, eat, homework, bathe, bed.
It was almost just as well. There was ~nowhere for them to go past the yard (and 92°/90% humidity+heavy gnats).
