"One acre of trees annually consumes the amount of carbon dioxide equivalent to that produced by driving an average car for 26,000 miles. That same acre of trees also produces enough oxygen for 18 people to breathe for a year."
- New York Times
" A 100-ft tree, 18" diameter at its base, produces 6,000 pounds of oxygen."
- Northwest Territories Forest Management
"On average, one tree produces nearly 260 pounds of oxygen each year. Two mature trees can provide enough oxygen for a family of four."
- Environment Canada, Canada's national environmental agency
"Mean net annual oxygen production (after accounting for decomposition) per hectare of trees (100% tree canopy) offsets oxygen consumption of 19 people per year (eight people per acre of tree cover), but ranges from nine people per hectare of canopy cover (four people/ac cover) in Minneapolis, Minnesota, to 28 people/ha cover (12 people/ac cover) in Calgary, Alberta."

I don't think aging on a homestead is a challenge. I watched my grandma age into her nineties on her farm. She only became a burden the last year of her life. She was in a wheelchair a year or two, I can't remember. She "processed food" in the kitchen before that. They caught her in the hayloft gathering eggs when she was 90.
I think the biggest challenge in longterm homesteading is the isolation. I know one woman cut off at the waist (diabetes) who is nothing but a "stub" of a body, yet she chops wood and keeps her own fire going all winter. Whenever I feel pity for myself, I think of her. She does have family members who visit regularly. One day they found her upside down between two rails on the staircase. They described her being incredibly defiiant the day she was amputated. When they family went to look in on her right after surgery, she was sitting up on her stump glaring at them.
I never met the woman, but her relatives talk about her all the time.
I don't have diabetes, but if I did, she would be a role model. The problem is, relatives die off, and the homesteader is left isolated unless in a community. That's my case, but I would rather be alone in the woods any day than with a million lost souls in a city.
