Env. 'Prevention' Agency Enables Corporate Eco-rapists

It's no accident that factory farms have spread across the country. Weak environmental rules and bad farm policy have allowed factory farms to take over livestock production. Even if you don't live near one, there are things you can do to help get rid of factory farms.
Factory farms are regulated under a patchwork system that leaves communities vulnerable to often indifferent and underfunded state environmental enforcement. Factory farm permitting rules released by the Environmental "Prevention" Agency (EPA) in 2008 only require permits for facilities that declare their intention to release manure directly into waterways. Common manure management practices -- like cesspool lagoons and applying manure to cropland -- don't require any permit at all.

Communities across the country are suffering from water contaminated by manure lagoon failures, waste seeping into aquifers, runoff from oversprayed fields and air pollution from overcrowded livestock operations.

Can you tell the EPA that it is time to regulate factory farms?

Native Plants: Restoring to an Idea


by Toby Hemenway

(presented at the Native Plants and Permaculture Conference, Lost Valley Educational Center, Dexter, Oregon, in May 2007.)

Let me tell you about the invasive plant that scares me more than all the others. It’s one that has infested over 80 million acres in the US, usually in virtual monocultures. It is a heavy feeder, depleting soil of nutrients. Everywhere it grows, the soil is badly eroded. The plant offers almost no wildlife habitat, and since it is wind pollinated, it does not provide nectar to insects. It’s a plant that is often overlooked on blacklists, yet it is responsible for the destruction of perhaps more native habitat than any other species. Research shows that when land is lost to this species, native plants rarely return; they can’t compete with it. It should go at the top of every native-plant lover’s list of enemies. This plant’s name: Zea mays, or corn. Corn is non-native. It’s from Central America. Next on my list is the soybean, with 70 million acres of native habitat lost to this invasive exotic. Following those two scourges on this roll call of devastating plants is the European invader called wheat.

Wait, you say: these plants are deliberately spread by people; that’s different! But to an ecologist, it is irrelevant that the dispersion vector of these plants is a primate. After all, we don’t excuse holly or Autumn olive, even though without bird dispersal, they could not spread. Why are corn, soy, and wheat not on any blacklists? Because we think of them differently than plants spread by non-humans. This suggests that an invasive species is an idea, a product of our thinking, not an objective phenomenon. When we restore land, we restore to an idea, not to objective criteria.

Chains...my Mama's got me locked up in chains...

Top of the Food Chain

by Richard Heinberg on November 25, 2008

Food webToday comes the startling news of a British government report showing a drop in oceanic zooplankton of 73 percent since 1960.

For many people, this may seem relatively inconsequential as compared to daily cataclysmic revelations about the state of the national and global economy. This reaction is understandable: we care first and foremost about our own immediate survival prospects, and a new and greater Depression will mean millions losing their homes, millions more their jobs. It's nothing to look forward to.

It takes some scientific literacy to appreciate the implications of the catastrophic loss of microscopic sea animals. We need to understand that these are food for crustaceans and fish, which are food for sea birds and mammals. We need to appreciate the importance of the oceanic food web in the planetary biosphere.

At the top of the global food chain sits a species that we really do care about—Homo sapiens. The ongoing disappearance of zooplankton, amphibians, butterflies, and bees is tied directly or indirectly to the continuing growth of our own species—both in population (there are nearly seven billion of us large-bodied omnivores, more than any other mammal) and in consumptive voracity (water, food, minerals, energy, forests—you name it).

It's at this point in the discussion that some of us start feeling guilty for being human, and others of us tune the conversation out because there's apparently not much we can do to fundamentally change the demographic and economic growth trends our species has been pursuing for hundreds, if not thousands of years.

But the current economic Armageddon (that we care about) is related to human-induced biodiversity loss (that many of us don't notice) in systemic ways. Both result from pyramid schemes: borrowing and leveraging money on one hand; on the other, using temporary fossil energy to capture ever more biosphere services so as to grow human population and consumption to unsustainable levels. Our economic pyramid is built out of great hewn blocks of renewable and non-renewable resources that are being made unavailable to other organisms as well as to future generations of humans.

The financial meltdown tells us these trends can't go on forever. How the mighty have fallen!—Masters of the Universe reduced to begging for billion-dollar handouts in front of a television audience.

Next will come a human demographic collapse (resulting from the economic crisis, with poor folks unable to afford food or shelter), as mortality begins to exceed fertility.

In all of this it's important to remember that the species on the lower levels of the biodiversity pyramid have been paying the price for our exuberance all along.

The pyramid appears to collapse from the top, while in fact its base has been crumbling for some time.
