a hectare of trees captures 1 to 10 tonnes of CO2 per year (http://www.sicirec.org/definitions/carbon-capture http://www.sicirec.org/definitions/carbon-capture)

a hectare of trees captures 1 to 10 tonnes of CO2 per year (http://www.sicirec.org/definitions/carbon-capture http://www.sicirec.org/definitions/carbon-capture). That's about 7500 square meters of forest per person (assuming 11 tons per person per year). It's theoretically doable, but would require enormous forests.
