Land Use Change over the years
According to the Woods Hole Research Center, about 100 Pg (one petagram = 1 billion metric tons) of carbon (not carbon dioxide, petagram 1 billion metric tons) of carbon (not carbon dioxide, which is much heavier) were released into the atmosphere from changes in land use world‐wide between 1860 and 1990.
