Global Population


Adapted from Wikipedia


The world population is the total number of living humans on our Earth. As of 2010, the world population was estimated at 6.916 billion. The United States Census Bureau estimated that the world population exceeded 7 billion on March 12, 2012. The average age of the world's population was estimated to be 29.7 years in 2014.


World population has experienced continuous growth since the end of the Great Famine and the Black Death in 1350, when it was near 370 million people. 


The global growth rate peaked at 2.2% in 1963, and has declined to 1.1% as of 2012. Total annual births were highest in the late 1980s at about 138 million and are now expected to remain essentially constant at their 2011 level of 134 million Total number of deaths are 56 million per year and are expected to increase to 80 million per year by 2040.


2012 UN projections show a continued increase in population in the near future with a steady decline in the rate of population growth. The global population is expected to reach between 8.3 and 10.9 billion by 2050.


Some analysts have questioned the sustainability of further world population growth highlighting the growing pressures on the environment, global food supplies, and energy resources.

Global Food Security


Adapted from Wikipedia


Food security is a condition related to the supply of food and our access to it. Concerns over food security have existed throughout history. There is evidence of granaries being in use over 10,000 years ago. Central authorities (governments) in civilizations including ancient China and Egypt were known to release food from storage in times of famine. Therefore, food security is concerned with storage and resourcefulness.


Fuel shortages, economic instability, and wars cause food shortages. In the years 2011-2013, an estimated 842 million people were suffering from chronic hunger. The Food and Agriculture Organization of the United Nations, or FAO, identified the four pillars of food security as availability, access, utilization, and stability. Violence may be the main cause of hunger in the world today. Access to food requires a peaceful community.

Follow up ~ Try to make some of your own questions regarding food security.

Confronting a host of major crises relating to climate, energy, poverty, food, economic conditions, and political instability, why should anyone be concerned about population?  Perhaps the answer is obvious. Most of the problems that confront the world today relate in some critical way to population growth and lack of resources.


While public concern about rapid population growth has subsided in recent decades, world population is still growing at about 80 million people a year, or about 220,000 people per day.  If current trends persist, there will be 2.5 billion more people on the planet by mid-century, bringing the total to about 9.2 billion. That projected population growth raises a host of questions about the future of humanity and the planet in which we inhabit.
