A. Human Activity
"According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun's heat and causing the planet to warm. Evidence shows that 2000 to 2009 was hotter than any other decade in at least the past 1,300 years<span>. This warming is altering the earth's climate system, including its land, atmosphere, oceans, and ice, in far-reaching ways."

Answer:
Correct answer is 4. Under 2.5 people per sq. mi. (VERY low density)
Explanation:
Option four is the correct because areas such as Sahara have a low density and are not populated. The conditions of living are not allowing people in these type of areas to create some larger permanent settlements. The similar case is for example in Australia where 3/4 is covered with desert, which is practically uninhabited. Or we can also created a parallel with Greenland which also has a low density due to climate factor.
Geography is basically the study of the Earth/ World
