Lecture 13
Population, Consumption, and the Environment
Are GMO’s the solution?
Do you think you think that GMO’s are the solution to social problems or a social problem in themselves?
Every society makes choices about the technology that is used. Where the choices should be made about GMO’s – the ballot box (our votes) or the marketplace (our money)?
The Tragedy of Commons
Commons: Something open and shared by all
“The Invisible Hand”: Individual selfishness leads to greatest public interest Corporations are legal persons, rationally organized for the
goal of profit maximization “Empire of the Pigs”
"Mr. Greenspan said that he had found “a flaw in the model that I perceived is the critical functioning structure that defines how the world works.”
Are GMO’s the solution to world hunger?
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 and Food Insecurity Inequitable ownership of resources Destruction of traditional food production Environmental decline Import/Export Imbalance
Hungry in Chad
Hungry in Guatemala
Hungry in the USA
Western Diet
American diet is characterized by: Animal products Processed foods Eating out
Americans get 60% of their energy from two nutrients
Fat: oil from soybeans Sugar: high fructose corn syrup
Effects of the Western Diet
Inequality in distribution of resources around the world 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 33% more fossil fuel
Polarization of Nutritional Health Diseases of over-consumption Diseases of under-consumption**Now more over-weight than under-weight**
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
Growing Consumption
Inequality in global consumption In industrialized countries increase 2.3% annually East Asia – 6.1% African’s consume 20% less today than 25 years
ago
Growing demands on the environment with the growing population of new consumers Increase desire for consumer goods of Western
lifestyle and “consumer culture”
How do we pursue the common good?
Effect on the Land
Water Resources
Loss of Forests
Carbon Emissions
