America is waking up to the fact that the unfathomable amounts of animal dung generated by our industrial agricultural system is poisoning our water and our air.  Those who live by waters polluted by the excesses of industrial agriculturae have long understood the grim connection between our cheap-food system and the slow death of rivers, lakes, streams, estuaries, and other coastal waters.  Now the mainstream media is bringing wider attention to this looming environmental disaster.

Exhibit A:  The Washington Post recently ran a prominent environmental expose under the headline “Manure becomes pollutant as volume grows” This excerpt explains the problem well:

Animal manure, a byproduct as old as agriculture, has become an unlikely modern pollution problem,….The country simply has more dung than it can handle: Crowded together at a new breed of megafarms, livestock produce three times as much waste as people, more than can be recycled as fertilizer for nearby fields.   That excess manure gives off air pollutants, and it is the country’s fastest-growing large source of methane, a greenhouse gas. And it washes down with the rain, helping to cause the 230 oxygen-deprived “dead zones”

"Dead zones" are areas within waterbodies where oxygen becomes severely depleted when massive algae colonies--fed by nutrient-rich manure and other agricultural waste--die off. The oxygen-depleting algae decomposition process has disastrous results for fish and other aquatic life. This fishkill occured on the Neuse River in North Carolina an area of intensive factory farming.

Exhibit B: Popular talk radio host and TV personality Don Imus featured an unusually-sobering interview with investigative author David Kirby about his new book “Animal Factory.”  In vivid detail, the author explained the inhumane conditions in which thousands of hogs, cows, and chickens are often confined at these industrial meat and dairy operations that are much more akin to factories than “farms.”  Citing many gasp-inducing horror stories from the book, Kirby underscored the public health and environmental risks created by the oceans of excrement these operations release into the environment when they saturate spray fields with levels of liquid manure that runs off into nearby rivers, streams, and lakes.

Exhibit C: Through the international success of documentary film “Food, Inc.,” which is nominated for a “Best Documentary Feature” Academy Award millions of moviegoers were exposed to moving pictures of the environmental and social repercussions of industrial agriculture.

Defenders of industrial agriculture will tell you that spraying liquid manure on to pastures and cropland helps to fertilize that land to grow crops to feed the animals.  In reality, spraying massive amounts of liquid manure on the land is a cheap way for these industrial farms to dump their wastes.  The rest of us bear the true costs in the form of water that is unsafe for drinking, swimming, and fishing among other public health risks and other pollution problems.

Liquid manure is spread to saturation levels on a farm on the shores of Lake Champlain's St. Albans Bay, a part of the lake that has long suffered from algae blooms. Though blooms have yet to cause fishkills on the scale pictured above, scientists have documented a growing "dead zone" in the Lake's Northeast Arm--an area where manure from thousands of dairy cows is spread on riverside and lakeside cropland during much of the year.

This problem is coming to a head in Vermont, where lax regulation and poor management of industrial-scale dairy operations contributes pollution that feeds annual outbreaks of blue-green algae and nuisance weeds in Lake Champlain and is also responsible for bacteria contamination in the Lake and many other rivers and streams.  We would never allow unchecked pollution like this from any other industry, but the powerful agribusiness lobby has largely prevented the type of legislative and law-enforcement responses that this problem demands.  To learn more about CLF’s actions to document and force clean up and prevent a worsening of this dung disaster, read our report ”Failing Our Waters, Failing our Farms,” and the legal petition sent to EPA seeking stronger action under the Clean Water Act.   And check back here for a future post on other ways to get our society out of this dung dilemma.
