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

Loss of Forests
