According to the EPA, fossil fuel use is the primary source of carbon dioxide, CO2. The way in which people use land is also an important source of CO2, especially when it involves deforestation. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture and degradation of soils. Likewise, land also can remove CO2 from the atmosphere through reforestation, improvement of soils and other activities.
