Foodmile |
distance food travels from the location where It is produced to thelocation here I is consumed. |
|
|
Trendsin food miles (Why have food miles increased? |
pushing farms, farther out, we can ger things farther, the number offarms have dropped, 1. Consolidation of farms. We have fewer but larger farms, 2. Food passes through a complex series of centralized producers, processors,distirbutors and transproters before it reaches the consumers. |
|
|
Globalfood markets (Why did they develop? |
developed because prices. They produce these foods in bulk which drivesprices down. |
|
|
global food market consequences |
quality ofthe product, long term shipping= lessfresh, products are picked before they are ripe or treated with preservations.Small local farms cannot compete with the volume being produced over seas, bigdistributors drive prices down. |
|
|
Impactof buying local |
depends on howlocal food is, how it is produced, and how it is transported. Sometimesregional produce is a better idea because it uses more efficient transportationtechnology (fewer trips), sometimes-non local food may be preferable becausethey may use cleaner or more efficient production methods |
|
|
Sustainableagriculture- |
the goal is to provide food and fiber on a long term sustainable basisand to restore damaged farmland. Local food helps with this but there may beother social environmental trade offs |
|
|
Organicfood (Is it the solution?) |
food grown without synthetic fertilizers or pesticides, these areusually made from fossil fuels. |
|
|
Whydo we use so much energy in food systems |
herbicides and pesticides are created through an energy intensiveprocess, food miles require energy. WE use significant energy producing anddistributing food. |
|
|
Fossilfuels and their lifecycle |
Fossil fuels and their lifecycle – fossil fuels = coal,oil, natural gas, oil shale, tar sands. Derived from decayed remains of plantsand aniamls buried millions of years ago. Heat, pressure, time transforms theminto fuels |
|
|
Energytrends in MDCs and LDCs (Also: Why do we use so much |
80% of the worlds natural gas, 65% of worlds oil, 50 percent of worldscoal. US uses about 25 percent of worlds oil. Because modern industrial andagricultural operations require high energy inputs. |
|
|
Majorconsumers of energy in the US: Industrial, transportation, buildings- |
industry: mining, milling, smelting, forging of metals, chemicalindustry a big consumer, cement, glass, bircks, tile, apper, processed foods. Transportation:we consume almost 19 million barrels of oil per day. About 71% of which goesfor transportation |
|
|
Historicaldevelopment of energy sources over time |
in 1890 wood supplied 90% if all energy in the US, wind power criticalfor transportation, water used to power mills, coal |
|
|
Advantagesand drawbacks of fossil fuels, in general |
advantages: accesibily drill and mine, utility easy to use, higherenergy content , transportability , conversion factor Disadvantges: they arefinite?, burning them casues air pollution, mining and drilling harmful toenvironment, transporting fuels can be dangerous |
