You need an enormous, full sun greenhouse just for one person’s CO2:
“An active person exhales about 1 kg of CO2 per day. So, you would need 1000 square meters of grass to absorb one person's CO2. That's a square about 32 meters on a side, or in archaic units, a quarter acre. A one-square-kilometer park could support 1000 people, just with the grass.“

(Or: Need about 16 trees per person.)
