Under the Influence of Ethanol

Ethanol is even more popular now than when Americans made it to fuel themselves rather than their cars, and some of the behavior it generates is no less silly. The cornbelt, Congress and the departments of Energy and Agriculture are hawking the stuff as if it were Dr. Kickapoo's Elixir for Rheum, Ague, Blindness and Insanity. Bill Gates has invested $84 million in it. In the last five years the amount of corn poured into ethanol distilleries has tripled to 55 million tons. At this writing, projections by the Department of Agriculture have world grain use growing by 20 million tons in 2006, 6 million tons of which will be consumed by the world's rapidly proliferating and hungry human beings, 14 million tons of which will be consumed by America's proliferating and gas-guzzling cars. Eighteen percent of all the corn we grow goes into ethanol production, and goals mandated by Congress will sharply increase that percentage.

It all started in 1990 with amendments to the Clean Air Act, revolutionary in that they regulated not just how we burn gasoline but how we make it. In areas out of compliance with air-pollution standards, gasoline had to include at least two percent oxygen-containing chemicals (oxygenates), the better to combust carbon monoxide, toxic hydrocarbons, and smog-producing volatile organic compounds. There were only two choices--ethanol and the petroleum-based methyl tertiary butyl ether (MTBE). This was precisely what the cornbelt had fantasized about and lobbied for. Suddenly the moribund ethanol industry had a future. City air would become breathable. We'd have plenty of fuel. It was going to be a win-win-win.

But instead of cleaning up America, ethanol has added to the mess we're making out of our water and air. Now the Bush Administration has decreed that ethanol replace the far more efficient MTBE as an oxygenate. But with current refining technologies and anti-pollution paraphernalia on motor vehicles there's no need for any oxygenate, a fact the powerful agribusiness lobby doesn't want you to know. Under its withering pressure, Congress and the executive branch have committed the nation to ethanol as both oxygenate and fuel.

The Energy Policy Act of 2005 requires that US gasoline contain 7.5 billion gallons of ethanol by 2012, up from 4 billion. One hundred and one ethanol plants are online, and 44 are under construction. Eighty million US acres were planted to corn in 2006; and the ethanol boom will require 10 million more just in 2007. Ethanol, we are being told, is going to "reduce our dependence on foreign oil" and "lead us to energy independence." "Live Green, Go Yellow," effuses General Motors, one of the major roadblocks to fuel-efficiency standards. "Fill Up, Feel Good," gushes the Ethanol Promotion and Information Council, a front for agribusiness.

How will ethanol affect your fishing, apart from possibly ruining your outboard motor? (Ethanol does this in lots of ways. Just ask David Blinken, the famous Montauk fly-fishing guide, who recen-tly spent $25,000 pulling his deck, replacing his fuel lines and tank, extracting aluminum-oxide gum from his carburetors and basically rebuilding his twin 100-horse Yamahas.) First, no crop grown in the United States consumes and pollutes more water than corn. No method of agriculture uses more insecticides, more herbicides, more nitrogen fertilizer. Needed for the production of one gallon of ethanol are 1,700 gallons of water, mostly in the form of irrigation taken from streams either directly or by snatching the water table out from underneath them. And each gallon of ethanol produces 12 gallons of sewage-like effluent.

Ethanol plants are gross polluters of air and water, and because of the exorbitant price of natural gas some of the new ones will be coal-fired, adding to the already dangerous mercury content of fish. The response of the Bush administration has been a proposal to relax pollution standards for ethanol production. Under the conservation programs of the 1985 Farm Bill and its successors, some farmers are bootstrapping their way toward sustainable agriculture, but corn production still erodes topsoil about 10 times faster than it can accrete.

The toxic, oxygen-swilling stew of nitrates, chemical poisons and dirt excreted from the corn monocultures of our Midwest pollutes the Mississippi River and its tributaries, limiting fish all the way to the Gulf where it creates a bacteria-infested, algae-clogged, anaerobic "Dead Zone" lethal to fish, crustaceans, mollusks and virtually all gill breathers. In some years, depending on seasonal heat and water conditions, the Dead Zone can cover 8,000 square miles. And it's expanding.

No habitat is more important to fish and wildlife than wetlands. They filter out pesticides and sediments, and they consume phosphates and nitrates. At least 70 percent of the wetlands in the cornbelt have already been lost. But, in order to produce surplus corn for ethanol, remaining cornbelt wetlands are being drained. In some areas--Nebraska, for instance--corn has to be irrigated by pumps that suck water from the ground faster than it percolates back in. Both pumps and the ethanol plants themselves are powered by natural gas, the frenzied production of which is creating horrendous problems for fish and wildlife in the West.

Where is the land to grow all the extra corn needed for ethanol supposed to come from? Well, the Bush administration has an idea: In testimony to Congress, the USDA's chief economist, Keith Collins, has raised the possibility of using land enrolled under the Farm Bill's Conservation Reserve Program (CRP). Not so coincidentally, it happens that this is precisely the idea that the corn lobby had come up with. In an op-ed in the December 6, 2006 Des Moines Register Bruce Rastetter, CEO of Hawkeye Renewables, Iowa's largest ethanol producer, writes: "First, the government should immediately release some of the 37 million acres that now sit idle in the US Department of Agriculture's Conservation Resources [sic] Program."

"We're hearing rumors every day that the [USDA's] Farm Services Agency is on the verge of announcing they're going to allow people to liquidate CRP contracts to grow more corn for ethanol," says Julie Sibbing, point person for the National Wildlife Federation's agriculture and wetlands program. "That's a huge concern. They've been studying CRP to see if there's land they can pull out to grow more corn. We're hearing from folks up in the plains that farmers are going in and breaking up virgin prairie. It's lousy land for agriculture, but they're planting it because of the high price of corn brought on by this ethanol boom. It's scary. And there are huge water requirements. People are building these ethanol plants anywhere, paying no attention to the water needs. We're worried about instream flows."
