Unformatted text preview: 2d. The 5.3% seems small. It matters because addition of CO2 to atmosphere by human activity disrupts the natural cycle of carbon. 2e. 1.13% = CO2 from fossil fuels/CO2 in land plants; 0.0166% = CO2 from fossil fuels/CO2 stored in ocean; 0.0000063% = CO2 from fossil fuels/CO2 stored in marine sediments and sedimentary rocks. 2f. Even though human interference to carbon cycle is relatively minimal, the extra addition of CO2 into the atmosphere will eventually harmfully affect global ecology. 3a. Missing carbon sink describes the amount of CO2 absorbed or lost through some kind of indefinable process. 3b. It is important to clarify how much of missing carbon sink is due to oceanic or terrestrial region. Unbalanced carbon cycle is a global problem, and it is important to know how it is exactly working. Knowing how much each region contributes to sinking of CO2 will help scientists understand at where and of how much the unbalance of CO2 cycle occurs....
