Population, Consumption, and the Environment
How many planets would it take to support your level consumption?
What categories did you consume the most? How can you change this?
How do you compare to people similar to you? Different than you?
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
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”
Effect on the Land
Water Resources
Loss of Forests
Carbon Emissions
