Summary: This short video, "The Challenge Ahead: Rising Numbers, Shrinking Resources," accompanies a five-part series from the Los Angeles Times and highlights the causes and consequences of the global population explosion. Demographers anticipate continued population growth driven by the reality that there are now 3 billion people on the planet under the age of 25, and about 1.2 billion of them are adolescents who are entering their reproductive years. Projections suggest that by 2050 there will be well over 9 billion people on the earth, and the video highlights many of the resource demands of this many people. For instance, Jonathon Foley of the Institute on the Environment asks, "how are we going to feed 9 billion people without trashing the planet?" and Joel E. Cohen notes that humans are currently consuming resources on planet earth as if the earth were about 50% more productive. The connection between consumption (and production) and population is also explored in Foley's 2011 Ted Talk, where he reports that the total area humans are currently using for agriculture is about the size of South America (16 million square kilometers), while the total area used as pasture and range land is about the size of Africa (30 million square kilometers). Humans are also currently using about 50% of Earth's fresh water, and of this share, about 70% is used for agriculture. But after connecting population growth to agricultural demands, it is only a short distance to discussions exploring the connections between population and environmental degradation, or even climate change. After all, as Foley also points out in his Ted Talk, agricultural activity is by far the largest contributor of greenhouse gases. Thus "The Challenge Ahead" is an excellent teaser for any introduction to the field of demography, and it can be used to spur discussion about the importance of the field for tackling some of the most formidable challenges of the twenty-first century. Note that The Sociological Cinema has previously recommended clips that explore problems associated with population (here, here, and here).
