Biosequestration is the capture of atmospheric carbon by photosynthesis. It is crucial to the initiation, evolution and preservation of life.
Carbon in the Earth's atmosphere
It is generally accepted by geochemists that the carbon dioxide content of the atmosphere since before the industrial revolution was 0.03 percent. The capture of atmosphereic C02 level has been largely a function of absorption by sea water, vegetation and soils. The capacity of the oceans to absorb C02 is decreasing. Given the potential adverse effects of rising atmospheric C02 levels (see climate change) this increases the importance of developing policies and laws that increase photosynthesis and biosequestration.
Enhanced photosynthesis
Biosequestration may be enhanced by improving photosynthetic efficiency by modifying RuBisCO genes in plants to increase the catalytic and/or oxygenation activity of that enzyme.
