Trees are the number one way in which carbon can be removed from the atmosphere and stored in vegetation over the long term. A single tree can absorb CO2 at a rate of 48 pounds per year. Because of this, the carbon footprints of 18 average Americans can be neutralized by one acre of hardwood trees. And it has been found that managed forests accumulate more carbon per acre than unmanaged forests.
Many people compost their food scraps and yard waste because they think it is the right thing to do. In some places, like San Francisco and Seattle, there is curbside pickup available to have these organic materials composted.
