"Big deal. If gas prices get high, I’ll just drive less. Why should I give a damn?"
Because petrochemicals are key components to much more than just the gas in your car. As of the year 2002, approximately 10 calories of fossil fuels are required to produce every 1 calorie of food eaten in the US. Source The size of this ratio stems from the fact that every step of modern food production is fossil fuel and petrochemical powered:
Pesticides and agro-chemicals are made from oil;
Commercial fertilizers are made from ammonia, which is made from natural gas, which is also peaking in the near future. Source
Most farming implements such as tractors and trailers are constructed and powered using oil-derived fuels.
Food storage systems such as refrigerators are manufactured in oil-powered plants, distributed using oil-powered transportation networks and usually run on electricity, which most often comes from natural gas or coal. Like oil and natural gas, coal too is peaking in the near future. Source
In the US, the average piece of food is transported almost 1,500 miles before it gets to your plate. Source In Canada, the average piece of food is transported 5,000 miles from where it is produced to where it is consumed. Source
A recent article published by CNN documented just how much fossil fuel energy is used to produce our food. Emphasis added:
In the U.S., up to 20 percent of the country's fossil fuel consumption goes
into the food chain which points out that fossil fuel use by the food system
in the developed world "often rivals that of automobiles". To feed an
average family of four in the developed world uses up the equivalent
of 930 gallons of gasoline a year - just shy of the 1,070 gallons that
same family would use up each year to power their cars. Source
According to the Organic Trade Association, the production of one pair of regular cotton jeans takes three-quarters of a pound of fertilizers and pesticides. Source
In short, people gobble fossil fuels like two-legged SUVs.
