It is so easy.
Clean air
Just move out of the city.
Clean water
Many of us already have this one licked. My uncles solved the almost 100 years ago. The hand dug wells in mountain springs, lined them with shale and dipped to cool clean water with a get this, a dipper.
Legitimately healthy food
You make this too hard, yes fresh organic produce is wonderful but even the regular stuff raised with artificial fertilizers, pesticides, herbicides and fungicides are great and healthy. Just eat more produce and less processed foods.
Truly sufficient sleep
We don't need to re-engineer the world for this just our lives. We are not slaves to culture. Just get some exercise so you are tired and free your mind from distractions, maybe a little meditation would help.
Loads of varied movement
Sure but even just moderate walking each day makes a big difference.
More nature
Sure walk in a park or a forest. Swim in a lake or a river. Get some sun but not too much. This one can be part of all of the above.
More human togetherness
This one is more problematic. Sometimes it is the people in are life that create all our problems.
