Carbon source
Any process that releases carbon dioxide into the atmosphere
Fossil fuels
Gases formed underground from the remains of once living organisms
Carbon dioxide sources
Burning coal oil gasoline and natural gas
Deforestation
Cement making
Methane sources
Coal mining production of petroleum products
Natural gas leaks

Nitrous oxide
Burning coal oil gasoline and natural gas
Fertilizer
Carbon sink
Any process that takes carbon dioxide from the atmosphere and stores it ex photosynthesis
Balanace is needed with carbon sources
Trees and water
