People have increasingly restored forests and adopted agriculture that, while larger scale, is higher yield, the researchers found. Many of the white areas correlate with the green, carbon-absorbing areas indicated on the animation above. As human land-use changed, industries and automobiles continued to steadily emit carbon dioxide that contributed to a botanical boom that further removed carbon from the atmosphere. Although a greenhouse gas and pollutant, carbon dioxide also is a plant nutrient.
