On average, a person consumes 430 g of oxygen per day and exhales 800 g of carbon dioxide. One hectare of green space absorbs about the same amount of carbon dioxide as 200 people breathe out, while releasing 80 kg of oxygen per day. How much oxygen per day is needed for residents of a city of 5 million people? What should be the area of green space in this city?

Solution
5,000,000x430g or 0.43kg = 2,150,000 kilograms of oxygen will be needed by residents per day.
1 hectare of plantations releases 80 kg of oxygen and absorbs 160 kg of carbon dioxide.
2150000kg / 80kg = 26875g; how much greenery is needed to evolve oxygen.
2150000kg / 160kg = 13437g; how much greenery is needed to absorb gas.
find the average:
26875ha + 13437ha = 40312ha;
40312 ha / 2 = 20156 ha;
Answer: 2,150,000 (for 1 question), 20156 (for 2).
