Like the illusion of Wall Street, with its vast and powerful investment banks, now shuttered, China too is an illusion perpetuated by the Globalists that gave us the 15,000 mile Caesar salad, poisoned cat food and lead based paint on babies' pacifiers. Like the illusion that money would come from thin air to always push housing prices higher, China has spent a generation pursuing its illusion. Pursuing an unattainable dream to be like the West, while 6000 years of its carefully shepherded top soil blows into the sea.

Fertilizers and pesticides are made from a base of petroleum or natural gas. Most of the nitrogen fertilizer farmers use today is made from natural gas. Pesticides are in a base of solvents made from petroleum.Oil and gas are organic carbon based molecules that can be synthesized and processed into many chemical compounds.

Maybe this information may be of help to see where petroleum is involved in the whole process of growing food:

Nonfuel Products

Nonfuel use of petroleum is small compared with fuel use, but petroleum products account for about 89 percent of the Nation's total energy consumption for nonfuel uses. There are many nonfuel uses for petroleum, including various specialized products for use in the textile, metallurgical, electrical, and other industries. A partial list of nonfuel uses for petroleum includes:


• Solvents such as those used in paints, lacquers, and printing inks
• Lubricating oils and greases for automobile engines and other machinery
• Petroleum (or paraffin) wax used in candy making, packaging, candles, matches, and polishes
• Petrolatum (petroleum jelly) sometimes blended with paraffin wax in medical products and toiletries
• Asphalt used to pave roads and airfields, to surface canals and reservoirs, and to make roofing materials and floor coverings
• Petroleum coke used as a raw material for many carbon and graphite products, including furnace electrodes and liners, and the anodes used in the production of aluminum.
• Petroleum Feedstocks used as chemical feedstock derived from petroleum principally for the manufacture of chemicals, synthetic rubber, and a variety of plastics.

Petrochemical Feedstocks

Petroleum feedstocks have been used in the commercial production of petrochemicals since the 1920's. Petrochemical feedstocks are converted to basic chemical building blocks and intermediates used to produce plastics, synthetic rubber, synthetic fibers, drugs, and detergents. Naphtha, one of the basic feedstocks, is a liquid obtained from the refining of crude oil.

Petrochemical feedstocks also include products recovered from natural gas, and refinery gases (ethane, propane, and butane). Still other feedstocks include ethylene, propylene, normal- and iso-butylenes, butadiene, and aromatics such as benzene, toluene, and xylene. These feedstocks are produced by processing products such as ethane (separated from natural gas), distillates, naphthas, and heavier oils.

Industry data show that the chemical industry uses nearly 1.5 million barrels per day of natural gas liquids and liquefied refinery gases as petrochemical feedstocks and plant fuel. 10 Demand for textiles, explosives, elastomers, plastics, drugs, and synthetic rubber during World War II increased the petrochemical use of refinery gases. Gas byproducts from the production of gasoline are an important source of many feedstocks.

Thank you for that very interesting information and for finding those links. It looks as though if we want a food system that doesn't rely heavily on fossil fuels, we all may have to have our own local gardens or whatnot so that shipping is less of a concern, etc., etc., etc.

Did you know that hemp can produce many of the products that oil can? Hemp can be used to make plastics, building supplies, some medicines, grooming products, oil, and well, you get the idea. The problem, though, is that industrial use of hemp was banned in 1937.

U.S.: No funds to keep up pesticide survey
Farmers and environmental groups agree it should be maintained
FRESNO, Calif. - Consumers and farmers will soon be on their own when it comes to finding out which pesticides are being sprayed on everything from corn to apples.
The U.S. Department of Agriculture said Wednesday it plans to do away with publishing its national survey tracking pesticide use, despite opposition from prominent scientists, the nation's largest farming organizations and environmental groups.
"If you don't know what's being used, then you don't know what to look for," said Charles Benbrook, chief scientist at The Organic Center, a nonprofit in Enterprise, Ore. "In the absence of information, people can be lulled into thinking that there are no problems with the use of pesticides on food in this country." …
Guess what's being sprayed today
