Reforestation is the restocking of existing depleted forests or in places where there were recently forests. Reforestation could save at least 1 GtCO₂ per year, at an estimated cost of $5–15 per tonne of carbon dioxide (tCO₂). Restoring all degraded forests all over the world could capture about 205 GtC (750 GtCO
2). With increased intensive agriculture and urbanisation, there is an increase in the amount of abandoned farmland. By some estimates, for every acre of original old-growth forest cut down, more than 50 acres of new secondary forests are growing. In some countries, promoting regrowth on abandoned farmland could offset years of emissions.
