Scientists estimate a safe oxygen consumption of 50 liters per hour for a human. Meanwhile, a leaf gives off about five milliliters of oxygen per hour. A person would need to be in a room with about ten thousand leaves. About 300 to 500 plants would produce the right amount of oxygen.
What plants need. How plants breathe. Just like people, plants need air in order to live. Human beings use lungs to breathe in a gas called oxygen and breathe out a gas called carbon dioxide. Without our lungs, we couldnât survive. Plants on the other hand, use their leaves and roots to breathe in carbon dioxide and turn it into clean, pure oxygen that humans and animals then breathe. If it werenât for plants, we wouldnât have enough oxygen!
