An average person uses 5,720 pounds of oxygen a day.
For the population of Rio de Janeiro, Brazil, you would need to plant 139,106,814 small plants to make enough oxygen for 1 day.
There are some logical concerns planting all of these plants in the HUGE city of Rio de Janeiro. One concern would be that there would be no space to plant over 139 million plants in this city. Rio de Janeiro is a big city while covering 486 sq miles in Brazil, Rio would have a lot of space you may think. But only having one big forest, the Tijuca Forest, everything else is just small homes with dirt and cement as roads. The Tijuca Forest is a hand-planted rain forest covering only 12.4 miles of 486 miles of Rio. The Tijuca Forest is the worlds largest urban rain forest. With all of Brazil having to overcome deforestation, that would probably be the only space that Rio de Janeiro would have to plant this gigantic amount of plants.
