Carbon sequestration is defined as how carbon is stored in plants, geological formations, soils, and the ocean. Carbon is stored in either solid or dissolved form—carbon stored either through natural processes or through anthropogenic activities that tend to convert to carbon dioxide gas. As climate change is exacerbated by excess carbon dioxide gas in the atmosphere, interest has been growing in carbon sequestration recently. More and more carbon is sequestered by changing land use, forestry, and geoengineering techniques.
