How is ocean acidification possibly linked to increased anthropogenic emissions of carbon dioxide (CO2 )?
A) Atmospheric CO2 combines with atmospheric moisture forming a light carbonic acid forms (H2CO3 ), that is precipitated over the world's oceans.
B) Increased photosynthetic activity in phytoplankton resulting from increased atmospheric CO2 concentrations results in acidification due to a complex chemical reaction during plant decay.
C) Oceans may absorb much of the rising concentrations of rising carbon, as dissolved CO2 mixes with water to form carbonic acid (H2CO3).
D) Thermohaline circulation exchanges carbon between surface dissolved organic carbon and deep layers of dissolved inorganic carbon.

There are many different strategies for reducing anthropogenic emissions of carbon. Determine whether the given strategy is an example of 1) energy efficiency and conservation; 2) a change in energy source; 3) a change in transportation energy source; or 4) an increase in natural carbon sinks.Bill decides to go "off the grid," installing photovoltaic (PV) cells on the roof of his house to generate his own electricity instead of relying upon the energy generated by the local coal power plant.
A. Energy efficiency and conservation B. Change in energy source C. Change in transportation energy source D. Increase in natural carbon sinks E. This is not a strategy to reduce carbon emissions
