"Bio-geoengineering is a form of climate engineering which seeks to use or modify plants or other living things to modify the Earth's climate.Bio-energy with carbon storage, afforestation projects, and ocean nourishment (including iron fertilization) could be considered examples of bio-geoengineering.Biogenic aerosols can be grown to replace those beneficial aerosols lost as the result of the death of 50% of Earth's boreal forests."@en .
