Try actually looking up the facts sometime. Bio fuel production does NOT take anything away from human food consumption, and is not behind commodity price hikes. Hor example, less than 1% of corn grown grown in the USA is used for human food consumption. In 2006 alone, we dumped 10 million tons of it because it went unsold. Most of the corn grown is used for animal feed, and the by product of ethanol product IS animal feed.
The USA is NOT a major food exporting country which "feeds the poor" all over the world. In fact, we import 74% of our food, and end up throwing more than half of that away.
What drives up commondity prices is the cost of growing them. fuel, fertilizer and machinery. Fertilizer alone had TROPLED in cost over last year, plus there is a shortage. Fuel prices have more than doubled, and machinery costs are out of this world.
Then there's the cost of transporting that commodity several times, from traders to brokers to food processors to grocery stores. Get who pays the fuel costs...
Even with wheat at $8 a bushel, farmers STILL aren't making any money, and are heavily subsidized. Just imagine what food would cost if subsidies were removed and farmers were paid for what it really costs to grow crops.
Oh and another thing, co2 is not a pollutant, Bio fuels are very clean burning. All that money spent making it and buying stays in America, not in some Arabs pocket. It will one day result in much less oil importing, eliminate farm subsidies and create a lot of American jobs.
It is all around good for America, which is why the left suddenly doesn't like it, and are spreading around food shortage scare stories to make you not like it either. They don't want you to drive anything that burns any kind a fuel. They want you to live in a crowded city, ride a bike wearing spandex and a dorky helmet.
Can we be a little more obtuse? The reason ethanol increases the output of CO2 is that it leads directly to deforestation, whereas burning the stuff only releases the carbon that went into growing the ethanol in the first place.
Not that I care in the least for the amount of CO2 in the atmosphere, I just mention it for the ironic value.
