The river is used as a major source of drinking water for Savannah and Augusta, to cool nuclear power plants in Georgia and South Carolina, and to generate hydroelectric power. Other uses include irrigation for agricultural crops and recreation.

Answer:
The correct answer is "3. Maximum sustainable yield"
Explanation:
Examining all the options,
The cost of bird nest soup cannot help people determine how many nests to harvest. By either increasing or decreasing the price, there is no direct or indirect effect on the peoples' ability to harvest the birds' nests.
International policies are those policies a nation sets up in order to protect their interest in the <em>international field. </em>The issue of nests harvesting might sometimes be a national issue. You cannot set up an international policy that would affect issues that occur nationally(within the auspices of the nation).
Maximum sustainable yield is the largest yield that can be taken out of a certain resource within a period of time. This concept can help people determine the number of nests to harvest because it tells them to stop when a particular number of nests have been harvested within a set time period.
The tragedy of the commons is a situation where shared-resources are over-consumed, spoiled and depleted by those who put their own self interest ahead of the interest of others. It cannot help the people to determine how many nests to harvest because if certain individuals are self-centered and ultimately greedy, they would go the extra mile to achieve their goal without considering the consequence of the birds extinction.
Fundamental niche of the cave swallow are the conditions it requires to survive and reproduce itself. However, there is an absence in the interaction with other species. This means that other species are not taken into account. This concept cannot help people determine how many nests to harvest, rather, <em>realized niche </em>may help.
The convection currents are formed due to heating of molecules.
When the liquid molecules are heated, the liquid becomes larger in size and lighter in weight. The heated molecules take up more space and rise to the top, while the cooler molecules comes to the bottom and takes the place. This cycle is known as the convection current.
Convection currents are the result of differential heating. Lighter which is less dense and warm material goes upward while on the other hand, heavier which is more dense and cool material sinks. This movement creates circulation patterns known as convection currents in the atmosphere.
