Sustainability and YOU!

So, what the heck is “sustainability?”
Sustainable/sustainability - (of economic development, energy sources, etc) capable of being maintained at a steady level without exhausting natural resources or causing severe ecological damage
SustainabilityThe ability to provide for the needs of the world's current population without damaging the ability of future generations to provide for themselves.
Ag Then
For thousands of years, crops/animals raised using methods that: Enhanced soil fertility, prevented pests, conserved water
These were considered sustainable methods because: Used indefinitely without depleting soil, defiling the
environment, or undermining health/quality of life
AKA responsible stewardship of the land and communities – think Ahupua’a System
Ag Now
Scientific innovations: Pesticides Genetically Modified Crops (GMOs) Concentrated animal feeding operations (factory
farms) Routine use of hormones and antibiotics in
livestock
Sustainable Farming produces foods that…
Are healthy to eat, being both nutritious and free of added toxins
Does not harm the environment and in many cases promotes environ. Health
Provides farmers with a fair wage Provides farm labor with fair wages and safe
working conditions Respects farm animals Supports and preserves rural communities (like
Waianae!!!)
When you buy and cook sustainable goods, you promote those principles!
Key Elements of Sustainable Farming
Minimize use of toxins Soil Conservation and Environmental
Stewardship Biodiversity Animal welfare Economically viable and socially just
Minimizing use of Toxins
Sustainable Natural, non-polluting
methods to control pests and weeds, chemicals used sparingly, never for organic certified farms
Antibiotics only administered to sick animals
Hormones not administered
Industrial 1 billion tons of pesticides
used in US every year Antibiotics routinely given to
animals to prevent diseases caused by extremely close confinement 25 million pounds - > 8x
amount used to treat disease in humans!!!
Hormones administered to speed animals’ growth
Soil Conservation
Sustainable What is taken out of soil
is replenished – crop rotation, cover crops, using manure/compost
Conserve soil via erosion-prevention methods
Minimal contamination from chemical pesticides, excess pesticides
Reduction in fossil fuel use
Industrial Continual loss of soil due
to extensive plowing and requires use of continual addition of synthetic fertilizers (fossil fuels), which can poison groundwater, surface water and the air
The Environment
Sustainable Preserving and enhancing soil fertility Do not raise more animals than the land is
capable of sustaining Using waste to fertilize land
The Environment
Industrial Concentrated Animal Feeding Operation (CAFO)
– produces a lot of waste, but not required to treat it!
Waste stored in tanks or lagoons, then used on surrounding fields, contaminates water, allows growth of algae,
EPA identified FF as source of pollution of more than 40% of nations lakes, rivers and streams
Industrial Ag also consumes water at an unsustainable rate
Environment, Con’t
A CAFO of 5,000 hogs can produce as much solid waste as 20,000 humans, but unlike cities, there is no sewage treatment plant!
Allowed to store waste in holding tanks or lagoons.
Result – water contamination and algae “blooms” that collapse fish and other aquatic populations

Maintaining Biodiversity
Sustainable Maintaining a wide
variety of plant and animal species
Rotation around farm Better protected against
natural disasters
Industrial Mono cropping – raising
just one or two types of plants
Vulnerable to pests and other conditions that can wipeout an entire crop
Animal Welfare
Sustainable Treated humanely Permitted to carry out
natural behaviors Fed diet appropriate to
their species
Industrial Animals confined in small
area, w/o access to fresh air, sunlight or open pasture
Unsanitary confinement results in widespread disease – hence antibiotics
Cows fed grain – not natural! Also bone meal leading to Mad Cow Disease!
Economically Viable (aka Profitable) Sustainable
Farmers must be able to earn a fair price for their goods and in turn able to pay workers a fair wage
Illegal immigrants?? Unregulated food from
other countries – China! Local communities benefit
when a farm is sustainable – Providing jobs and
purchasing supplies locally
Factory farms purchase equipment, supplies and feed from outside the region This causes stagnation in
rural communities – think Detroit where all the car factories are shut down because jobs have been outsourced to China or India. People who live in these communities cannot find jobs.
Socially Just
Sustainable Safe working
environment Animals treated
humanely Animals allowed natural
behaviors Fed appropriate diet
Industrial Factory Farms CAFOs Stranglehold on contract
farmers
Other Interesting Facts
Energy Consumption Sustainable farms minimize fossil fuel consumption Small-scale organic farming uses 60% less fossil fuel per
unit of food than industrial farms 17% of all fossil fuel consumed + 1/3 of greenhouse
gasses produced is directly related to food.
Property Values Houses close to CAFOs see property value of homes drop
as much as 40%.
Other interesting facts
Transportation Large-scale centralized food production requires
extensive transportation. Food may be transported as much as 1500 miles in
the US before reaching consumers. Therefore food grown are selected based on ability to
withstand long shelf life rather than flavor, diveristy or nutritional value.
Foods shipped long distances are more highly processed, supplemented w/ preservatives and require excessive packaging.

Definitions
Carbon Foot Print A carbon footprint is "the total set of
greenhouse gas (GHG) emissions caused by an organization, event, product or person."[1] Greenhouse gases can be emitted through transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services
Definitions, con’t
Global warming Continued rise in
average temperature of Earth’s atmosphere and oceans due to increase in greenhouse gases caused by deforestation/burning of fossil fuels
What are the implications of this?
Definitions, con’t
Greenhouse Gas Gases that may occur naturally or cause by
human activities that trap heat in the atmosphere CO2 –Carbon Dioxide – burning of fossil fuels, other
solids, trees/wood products, result of chemical processes (making cement)
Methane – livestock/other ag. Practices, decay of organic waste
N2O – nitrous oxide – ag practices and industrial activities
Fluorinated Gases – man made gases
Definitions, con’t
Fossil Fuel Fossil fuels are hydrocarbons, primarily coal, fuel
oil or natural gas, formed from the remains of dead plants and animals. (http://www.sciencedaily.com/articles/f/fossil_fuel.htm )
Is this a renewable resource?
Definitions, con’t
Factory Farming Refers to the raising of livestock in confinement at
a high stocking density (lots of animals packed into as little space as possible)
Definitions, con’t
GMO A genetically modified organism
(GMO) or genetically engineered organism (GEO) is an organism whosegenetic material has been altered using genetic engineeringtechniques. (wikipedia)
“Cloning” DNA inserted into another cell to make copies of gene Create an animal that is a “copy” of itself Therapeutic Cloning – embryo cloning used for
research
The question is…
How is Sustainability Demonstrated in Culinary Arts?
