Population, Consumption, and the Environment
Consumption and Inequality
"Today’s consumption is undermining the environmental resource base. It is exacerbating inequalities. And the dynamics of the consumption-poverty-inequality-environment nexus are accelerating. If the trends continue without change — not redistributing from high-income to low-income consumers, not shifting from polluting to cleaner goods and production technologies, not promoting goods that empower poor producers, not shifting priority from consumption for conspicuous display to meeting basic needs — today’s problems of consumption and human development will worsen.“- Human Development Report, UNDP

How many planets did you consume?
Adding More People to the Planet The world have 6.4 billion inhabitants today
Only 1.5 billion people a century ago Expected to add 3 billion more in the next 50 years
The total number of people on the planet is growing at a lightning pace and is expected to reach nine billion by 2050
Highest population growth is in Asia and Africa Lowest in North America and Europe
Growth Rates
Population Density
Too many people, too little food?
Malthus Theorem: population will always outpace food supply and produce human misery Negative checks: abortion, infanticide, prostitution Positive checks: war and famine
The solution: “moral restraint”
New Malthusians: fewer resources will lead to large scale misery and war over Water Land Oil
World Hunger Today
Food in an Unequal World
India (212 mill) and China (150 mill) have the highest # of undernourished people US: 38 million suffer from hunger, up 43% in the
last five years
Consistent World Hunger can be attributed to Inequitable ownership of resources Destruction of traditional food production Environmental decline Import/Export Imbalance
Hunger in the USA About 14% of people are food insecure in the USA
According the USDA, food security for a household means access by all members at all times to enough food for an active, healthy life. Ready availability of nutritionally adequate and safe foods,
and Assured ability to acquire acceptable foods in socially
acceptable ways, such as without resorting to emergency food supplies
Food stamps now feed 1 in 8 adults and 1 in 4 children In Santa Clara county food stamp use has increased 27%
since 2007 and today 4% of adults and 11% of children use food stamps
Hungry Planet
How we access and consume food is one of the best illustrations of the global inequality of consumption and the unequal impact on the earth’s resources
The book Hungry Planet: What the World Eats by photographer Peter Menzel and writer Faith D'Aluisio gives us a glimpse into these inequalities The following slides show a week’s worth of food for three
families around the world
Questions to Consider:
What is different/similar about all three families’ weekly food consumption?
In addition to the food, what else is being consumed (think of the what it takes to produce this food, bring it to consumers, and to store it)?
What impact do you these think these diets have on the planet and use of resources?

Growing Consumption
With a growing population of new consumers in areas like China and India, there are growing demands on the environment with the increase desire for consumer goods of Western lifestyle and “consumer culture” With growing incomes around the world there has
been growth in the demand for meat consumption, processed food, and other aspects of a “Western Diet”
Western Diet The Standard American Diet (SAD) is
characterized by: Animal products Processed foods Eating out
Americans get 60% of their energy from two nutrients
Fat: generally from oil from soybeans Sugar: generally from high fructose corn syrup
American Meat
“Americans eat about the same amount of meat as we have for some time, about eight ounces a day, roughly twice the global average. At about 5 percent of the world’s population, we “process” (that is, grow and kill) nearly 10 billion animals a year, more than 15 percent of the world’s total.”
Effects of the Western Diet
The Western Diet requires a large number of resources: 36 % percent of the world's grain goes to feed
livestock 1 calorie of meat takes 11-17 calories of grain 8 oz of beef take 660 gallons of water 70% of antibiotics used worldwide are used for
livestock production 33% more fossil fuel is used to produce meat than
grain
Affects on the Environment?
We share the Earth's natural resources with nearly 1 billion pigs, 1.3 billion cows, 1.8 billion sheep and goats, and 13.5 billion chickens
In the United States, where the waste generated by livestock is 130 times that produced by humans
World's livestock herds account for roughly 25 percent of anthropogenic greenhouse gases - more than driving our cars
Where does the Waste Go?
Global Polarization of Nutritional Health Another consequence of the unequal distribution resources around
the world is the polarization of nutritional health
Diseases of over-consumption plague consumer societies Heart disease, diabetes, obesity One recent study shows that there are now more over-
weight than under-weight people in the world
Diseases of under-consumption plague societies with low levels of consumption Hunger lowers immunity as is closes related to many
diseases such malaria, diarrhea, loss of vision, etc.
Linking the Social and the Environmental When we look at consumption of the world’s
resources we see significant inequalities in consumption patterns around the world “The richest 20 percent of the world’s population accounts
for 86 percent of private consumption expenditures, whereas the poorest 20 percent account for only 1.3 percent.”
The environment is a sociological issue because environmental sustainability requires both social and technological changes. Consumption patterns around the world are closely linked
to environmental problems, and therefore, are linked to the solutions.
