All three factors - increases in human population, increases in per capita fossil-fuel use, and land use changes - have contributed to the increase in CO2 emissions. More people means more demand for energy and resources, increased per capita fossil-fuel use leads to higher emissions, and land use changes, such as deforestation, reduce the Earth's capacity to absorb CO2.
