You breathe out about 215.46 kg (475 lbs) of carbon dioxide each year. Just to absorb the CO₂ in your breath, not considering the 20.40 tonnes (22.49 tons) the average American creates by burning fuels, requires 7 trees. To handle all the CO₂ requires 95 trees. We have already leveled over half the planet’s forests, which was suicidal considering we have only a minute fraction of the trees we need.
