Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Developing countries, notably those in Africa, will experience tremendous growth in population. These countries will likely face tremendous difficulties in supplying food, water, housing, and energy to their growing populations. As a result, a new source of electricity is needed. If one of the regions of the country has plenty of agriculture, rivers, and access to coal deposits underground. Which of the following would be the cheapest way for this region to make electricity, have minimal impact on the environment, yet not add carbon dioxide to the atmosphere?
A
Build a nuclear power plant in the middle of the region
B
Use the agriculture biomass to generate a renewable fuel that can be burned to generate electricity
C
Build dams along the rivers to generate electricity
D
Use the coal deposits to generate electricity in a few coal fired facilities
Explanation: 

Detailed explanation-1: -While death rates have fallen in many developing regions over the past several decades, birth rates remain high, which causes the populations of many countries-especially the poorest, least developed ones-to grow rapidly.

Detailed explanation-2: -Additionally, high population growth puts pressures on the soil by decreasing the time it is allowed to lay fallow; pastures land declines and the result is over grazing, which in turn causes in creased friction between farmers and herders.

Detailed explanation-3: -As the population has grown, the share of people living in developing countries has increased from 66% in 1950 to 83% now and should reach 86% by 2050.

Detailed explanation-4: -Population growth particularly will limit the amount of water available per person, because an increase in per capita water consumption driven by development will intensify water demand, straining the local water supply [17].
