True or False_______ There are more people alive today than at any point in Earth’s history._______ Earth’s population is evenly distributed across Earth._______ New York City is one of the most populous cities in the world. _______ The world’s population is increasing slower now than it has in the past._______ Population grows at different rates in different places._______ Less developed countries (LDCs) have lower life expectancies. _______ Overpopulation is a problem in all regions._______ Virtually all population growth is concentrated in less developed countries.

Population Concentrations / Sparsely Populated Regions

Human beings avoid clustering in certain physical environments. Relatively few people live in regions that are too dry, too wet, too cold, or too mountainous for activities such as agriculture. The portion of Earth’s surface occupied by permanent human settlement is called the ecumene.

Define ecumene:

What conclusion can you draw from the four maps?

Sparsely Populated Regions

Dry Lands. Areas too dry for farming cover approximately 20% of Earth’s land surface. The largest desert region in the Northern Hemisphere, extending from North Africa to Southwest and Central Asia is known by several names, including Sahara, Arabian, Thar, Takla Makan and Gobi deserts. A smaller desert region, in the Southern Hemisphere, comprises much of Australia.

Although dry lands are generally inhospitable to intensive agriculture, they may contain natural resources useful to people—notably, much of the world’s oil reserves. The increasing demand for these resources as led to a growth in settlements in or near deserts.

Wet Lands. Lands that receive very high levels of precipitation may also be inhospitable for human occupation. These lands are located primarily near the equator in the interiors of South America, Central Africa and Southeast Asia. The combination of rain and heat rapidly depletes nutrients from the soil and thus hinders agriculture.

Cold Lands. Much of the land near the North and South poles is perpetually covered with ice or the ground is permanently frozen. Consequently, the polar regions are unsuitable for planting crops, few animals and survive the extreme cold, and few human beings live there.

High Lands. Finally, relatively few people live at high elevations. The highest mountains in the world are steep, snow covered, and sparsely settled. In Switzerland, approximately half the land is more than 1,000 meters (3,300ft) above sea level, and only 5% of the country’s people live there. Some significant exceptions exist in Latin America and Africa, where higher lands are preferred due to temperatures.
