Native plants in your yard for native wildlife

Nature is not something out there, apart from people. It never was, and nowadays people have built and farmed and clearcut so much that wildlife species from insects to birds are in trouble. In south Georgia people may think that our trees make a lot of wildlife habitat. Actually, most of those trees are planted pine plantations with very limited undergrowth, and in town many yards are deserts of grass plus exotic species that don’t support native birds. Douglas Tallamy offers one solution: turn yards into wildlife habitat by growing native species. Since we are as always remodeling nature, we might as well do it so as to feed the rest of nature and ourselves, and by the way get flood prevention and possibly cleaner water as well, oh, and fewer pesticides to poison ourselves.

Douglas Tallamy makes a clear and compelling case in Bringing Nature Home: How You Can Sustain Wildlife with Native Plants

…it is not yet too late to save most of the plants and animals that sustain the ecosystems on which we ourselves depend. Second, restoring native plants to most human-dominated landscapes is relatively easy to do.

Some of you may wonder why native species are so important? Don’t we have more deer than we can shoot? Maybe so, but we have far fewer birds of almost every species than we did decades and only a few years ago.

Some may wonder: aren’t exotic species just as good as native ones, if deer and birds can eat them? Actually, no, because many exotic species are poisonous Japanese climbing fern on native Smilax to native wildlife, and because invasive exotics crowd out natives and reduce species diversity. From kudzu to Japanese climbing fern, exotic invasives are bad for wildlife and may also promote erosion and flooding by strangling native vegetation.

All plants are not created equal, particularly in their ability to support wildlife. Most of our native plant-eaters are not able to eat alien plants, and we are replacing native plants with alien species at an alarming rate, especially in the suburban gardens on which our wildlife increasingly depends. My central message is that unless we restore native plants to our suburban ecosystems, the future of biodiversity in the United States is dim.

Tallamy had an epiphany when he and his wife moved to 10 acres in Pennsylvania in 2000:

Crop rotation for profit

Want better yields and the same or more profit? Stop buying pesticides, rotate more crops over longer periods, and mix in animals. Yet another study confirms this. Oh, and a hundred times less disease-causing pesticides in streams, and presumably also less pesticides in the food going to market.

Mark Bittman wrote for NYTimes today, A Simple Fix for Farming,

The study was done on land owned by Iowa State University called the Marsden Farm. On 22 acres of it, beginning in 2003, researchers set up three plots: one replicated the typical Midwestern cycle of planting corn one year and then soybeans the next, along with its routine mix of chemicals. On another, they planted a three-year cycle that included oats; the third plot added a four-year cycle and alfalfa. The longer rotations also integrated the raising of livestock, whose manure was used as fertilizer.

The paper’s Figure 3 (above) illustrates that labor increased with crop rotation length, but so did yield, and profit remained the same or better. How can this be? Continue reading →

Pesticide studies hitting a nerve

There’s quite the controversy about that recent study that shows that “inert” ingredients in Roundup are actually toxic. Apparently Dr. Séralini hit a nerve.

Some critics are making up stuff:

EFSA logo “The EFSA requested access to the raw data” —Jon Entine

That turns out not to be true:

No. EFSA has not requested raw data for the study as this information is not required at this stage of the review process.” —EFSA.

Monsanto logo Who previously actually did refuse to release raw data?

Monsanto only released the raw data after a legal challenge from Greenpeace, the Swedish Board of Agriculture and French anti-GM campaigners.

Here’s the European Food Safety Authority (EFSA)’s rather vague statement about the recent study and EFSA’s FAQ clarifying that statement.

Here’s a much more substantive response from scientists supporting the Séralini cell toxicity study. The last item of that response:

GMWatch logo CRITICISM: GM has been in the food chain for years in the US. Why isn’t there evidence of people and animals suffering more tumours or dying earlier? Why aren’t Americans “dropping like flies?”

RESPONSE: Most GM crops are fed to farm animals, which have relatively short lives either for meat or dairy production and so there is probably not enough time for tumours to develop.

Americans have been eating GM food (soya, maize) for only a relatively short time in significant quantities in processed foods. So it may be too short a period for long-term effects such as tumour formation to be noticeable. However, we should also note that there is no labelling of GM foods in the USA and no monitoring of the population for ill-effects, so if GM food were causing ill health this would be going undetected.

Ill effects of Roundup went mostly unstudied until scientists in places like Austria (the first study above) and France (the second study) and Canada and Continue reading →

Roundup causes DNA damage even when vastly diluted

Roundup (you know, the stuff that’s sprayed on cotton, soybeans, peanuts, and corn and drifts across the road) causes DNA damage even when diluted down to 450 times less than what’s used in agriculture, according to a scientific study from February 2012.

Cytotoxic and DNA-damaging properties of glyphosate and Roundup in human-derived buccal epithelial cells, by Verena J. Koller, Maria Fürhacker, Armen Nersesyan, Miroslav Mišík, Maria Eisenbauer and Siegfried Knasmueller, Archives of Toxicology Volume 86, Number 5 (2012), 805-813, DOI: 10.1007/s00204-012-0804-8.

Glyphosate (G) is the largest selling herbicide worldwide; the most common formulations (Roundup, R) contain polyoxyethyleneamine as main surfactant. Recent findings indicate that G exposure may cause DNA damage and cancer in humans….

Since we found genotoxic effects after short exposure to concentrations that correspond to a 450-fold dilution of spraying used in agriculture, our findings indicate that inhalation may cause DNA damage in exposed individuals.

It’s probably not even the “active” ingredient, glyphosate, that’s causing this DNA damage, more likely one of its “inert” ingredients.

Parkinson’s and Roundup: latest in a long list

We already knew Argentinian farmers were suing Monsanto about Roundup-induced birth defects, including cerebral palsy, down syndrome, psychomotor retardation, missing fingers, and blindness; we knew Roundup’s active ingredient glyphosate was “a risk factor for developing Non-Hodgkin lymphoma”; we knew that Roundup-ready corn causes liver and kidney damage in rats and chickens fed feed including Monsanto corn show abnormal gene expression, and we knew that Roundup-ready corn is toxic to humans. Add to all that: Roundup is a risk for Parkinson’s disease.

Sayer Ji wrote for GreenMediaInfo 18 April 2012, Roundup Herbicide Linked To Parkinson’s-Related Brain Damage,

Alarming new research published in the journal Neurotoxicology and Teratology supports the emerging connection between glyphosate, the active ingredient in Roundup herbicide, and neurodegenerative conditions such as Parkinson’s disease and Parkinsonian disorders.

Published this month (April, 2012), the new study entitled “Glyphosate induced cell death through apoptotic and authophagic mechanisms,” investigated the potential brain-damaging effects of herbicides, which the authors stated “have been recognized as the main environmental factor associated with neurodegenerative disorders, such as Parkinson’s disease.”1

They found that glyphosate inhibited the viability of differentiated test cells (PC12, adrenal medula derived), in both dose-and-time dependent manners. The researchers also found that “glyphosate induced cell death via authophagy pathways in addition to activating apoptotic pathways.”

Roundup herbicide is now a ubiquitous contaminant in our air, rain, groundwater, and food, making complete avoidance near impossible. A growing body of experimental evidence now indicates that it in addition to its neurotoxicity it also has the following.

The whistleblowers show sued Fox (and lost)

Fox News hired Jane Akre and a couple of other reporters as an investigative unit and did a snazzy promo about that. The first case they investigated was Monsanto’s bovine growth hormone, RBGH. This is the whistleblower story behind the Fox Can Lie lawsuit.

ITN in the U.K. reporting about Health Canada’s report on bovine growth hormone:

Monsanto’s engineered growth hormone did not comply with safety requirements. It could be absorbed by the body, and therefore did have implications for human health. Mysteriously, that conclusion was deleted from the final, published version of their report.

That was for a product that U.S. EPA had approved with little or no testing. Fox’s investigative unit had the story, but Monsanto threatened to sue Fox. Watch the video for the details.

Eventually, Akre sued Fox. She won, but Fox won on appeal. An appeal that established that Fox can lie.

Want some 2,4-D with that drifting Roundup and Paraquat?

Got enough Roundup and Paraquat drifting onto you? Want some 2,4-D with that? If not, you can send your comments to USDA now. Hey, what if we all plowed under the mutant pigweed instead of breeding more with poison soup!

Tom Philpott wrote for Mother Jones 18 July 2012, USDA Prepares To Greenlight Gnarliest GMO Soy Yet,

In early July, on the sleepy Friday after Independence Day, the USDA quietly signaled its intention to greenlight a new genetically engineered soybean seed from Dow AgroSciences. The product is designed to produce soy plants that withstand 2,4-D, a highly toxic herbicide (and, famously, the less toxic component in the notorious Vietnam War-era defoliant Agent Orange).

Readers may remember that during an even-sleepier period—the week between Christmas and the New Year—the USDA made a similar move on Dow’s 2,4-D-ready corn.

If the USDA deregulates the two products—as it has telegraphed its intention to do—Dow will enjoy a massive profit opportunity. Every year, about half of all US farmland is planted in corn and soy. Currently, Dow’s rival Monsanto has a tight grip on weed management in corn-and-soy country. Upwards of 90 percent of soy and 70 percent of corn is engineered to withstand another herbicide called glyphosate through highly profitable Monsanto’s Roundup Ready seed lines. And after so many years of lashing so much land with the same herbicide, glyphosate-resistant superweeds are now vexing farmers and “alarming” weed-control experts throughout the midwest.

And that’s where Dow’s 2,4-D-ready corn and soy seeds come in. Dow’s novel products will be engineered to withstand glyphosate and 2,4-D, so farmers can douse their fields with both herbicides; the 2,4-D will kill the weeds that glyphosate no longer can. That’s the marketing pitch, anyway.

There’s more in the article.

It can also get into your well water, and then, according to EPA:

Greed is Good for Poisoning the Food Supply?

For many years big agro has treated the world’s health as an economic externality, a problem for somebody else that did not affect its own bottom line. That is starting to change, most recently in Argentina.

Anthony Gucciardi wrote for NaturalSociety 11 April 2012, Explosive: Monsanto ‘Knowingly Poisoned Workers’ Causing Devastating Birth Defects,

In a developing news piece just unleashed by a courthouse news wire, Monsanto is being brought to court by dozens of Argentinean tobacco farmers who say that the biotech giant knowingly poisoned them with herbicides and pesticides and subsequently caused ”devastating birth defects” in their children. The farmers are now suing not only Monsanto on behalf of their children, but many big tobacco giants as well. The birth defects that the farmers say occurred as a result are many, and include cerebral palsy, down syndrome, psychomotor retardation, missing fingers, and blindness.

This would be the same Monsanto that was convicted of chemical poisoning in France.

But this is once again far away in a small country of which we know nothing, right? Wrong:

The farmers come from small family-owned farms in Misiones Province and sell their tobacco to many United States distributors. The family farmers say that major tobacco companies like the Philip Morris company asked them to use Monsanto’s herbicides and pesticides, assuring them that the products were safe. Through asserting that the toxic chemicals were safe, the farmers state in their claim that the tobacco companies ”wrongfully caused the parental and infant plaintiffs to be exposed to those chemicals and substances which they both knew, or should have known, would cause the infant offspring of the parental plaintiffs to be born with devastating birth defects.”

Still, it must be some obscure poison only sold in the third world, right?

Wrong:

The majority of the farmers in the area used Monsanto’s Roundup, an herbicide with the active ingredient glyphosate that has shown to be killing human kidney cells. What’s more, the farmers say that the tobacco companies pushed Monsanto’s Roundup on the farmers despite a lack of protective equipment. In other words, these farmers — many in dire economic conditions — were being directly exposed to Roundup in large concentrations without any protective gear (or even experience or skills in handling the substance). Still, the farmers say the tobacco giants required the struggling farmers to ‘purchase excessive quantities of Roundup and other pesticides’.

That would be the same Roundup that farmers use around here all the time, without protective equipment. The Roundup we already knew was Continue reading →

Why Monsanto Thought Weeds Would Never Defeat Roundup

Wishful thinking. That’s why Monsanto unleashed crops and pesticides that are both poisonous to humans. Wishful thinking. Also known as greed.

Daniel Charles wrote for The Salt 11 March 2012, Why Monsanto Thought Weeds Would Never Defeat Roundup,

First, the company had been selling Roundup for years without any problems. Second, and perhaps most important, the company’s scientists had just spent more than a decade, and many millions of dollars, trying to create the Roundup-resistant plants that they desperately wanted — soybeans and cotton and corn. It had been incredibly difficult. When I interviewed former Monsanto scientists for my book on biotech crops, one of them called it the company’s “Manhattan Project.”

Considering how hard it had been to create those crops, “the thinking was, it would be really difficult for weeds to become tolerant” to Roundup, says Rick Cole, who is now responsible for Monsanto’s efforts to deal with the problem of resistant weeds.

So they thought small scale would be the same as saturating 90+% of every corn, soybean, peanut, and cotton field in the U.S. and numerous other countries with virulent poisons. Because they wanted the money.
