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 with 5 million people? What should be the area of green space in this city?
The inhabitants of the city require about 2,150,000 kg of oxygen. The area of plantations that emit this amount of oxygen will be equal to 26875 hectares.
