How much CO2 does a tree and Man take up?
A tree takes up about 2.52 lbs, or about 1150 grams of carbon dioxide daily on average[1]. This means that roughly one 25-year-old tree is required to take up CO2 exhaled by an average man and sustain bare breathing.
A conservative estimate based on a person who spends eight hours a day sleeping and 16 hours in normal activities, but one who does not add to the atmospheric burden by exercise, would thus come to about 456 liters of carbon dioxide a day, or 166,440 liters every 365 days.[2]
Approximately 912 grams per day.
