- Primary production (from wikipedia)
Primary production is the production of chemical energy in organic compounds by living organisms. The main source of this energy is sunlight but a minute fraction of primary production is driven by lithotrophic organisms using the chemical energy of inorganic molecules.
Global Carbon Cycle
- [NASA]
Each year, humans release more than 30-billion tons of carbon dioxide into the atmosphere through the burning of fossil fuels for powering vehicles, generating electricity and manufacturing products. Up to five-and-a-half additional gigatons of carbon dioxide are released each year by biomass burning, forest fires and land-use practices such as slash-and-burn agriculture. Between 40 and 50 percent of that amount remains in the atmosphere, according to measurements by about 100 ground-based carbon dioxide monitoring stations scattered across the globe. Another estimated 30 percent is dissolved into the ocean, the world's largest sink.
