Soil-Based Organic Agriculture Takes on the Climate Crisis, Economic Insecurity, and Health Inequity

Soil-Based Organic Agriculture Takes on the Climate Crisis, Economic Insecurity, and Health Inequity (Beyond Pesticides, March 4, 2020) 

'California produces the most food of any state in the U.S. – more than half of all domestic fruits and vegetables – but only 4% of its agriculture is organic. After releasing a report on the benefits of organic agriculture last year, the California Certified Organic Farmers (CCOF) Foundation is continuing to offer a “Roadmap to an Organic California” with an extensive policy report. The document proposes a wealth of concrete strategies for California lawmakers to employ. Organic agriculture, the authors skillfully reason, can respond to three pressing issues in California: climate resilience, economic security, and health equity.'

Chemical-Intensive Agriculture Increases Pregnant Mother’s Risk of Her Child Developing Leukemia

Chemical-Intensive Agriculture Increases Pregnant Mother’s Risk of Her Child Developing Leukemia   (Beyond Pesticides, March 3, 2020) 

'The findings are based on a review of pesticide use data in rural, agricultural areas of California, where many minority, low-income and farmworking communities live. Under current laws, the U.S. Environmental Protection Agency (EPA) permits the use of cancer-causing pesticides with an expectation that a certain number of cancers (anywhere from 1 in 1,000 to 1 in 1,000,000, based on the pesticide in question) should be considered ‘acceptable risk.’

"A statistical analysis conducted by researchers found that use of any carcinogenic pesticides within 4,000m (~2.5 miles)" (or 4 km for Canadians) "during a mother’s pregnancy increases the odds of the child developing acute lymphoblastic leukemia and acute myeloid leukemia nearly two-fold and three-fold, respectively. Urea-based herbicides, such as diuron and linuron, are found to be particularly troubling, substantially increasing the risk of childhood cancer.

Scientists also considered the cancer connection for several pesticides not considered carcinogenic by EPA, but widely used in California. Among those, glyphosate and and paraquat dichloride were both found to increase the risk of leukemia.'

'Researchers found that algae can develop resistance to contamination, but surviving phytoplankton communities are much less diverse. Diversity loss is cause for concern as it could hinder adaptation to other potential stressors, such as climate change.

Using experimental ponds, researchers first exposed some phytoplankton communities to low levels of Roundup over time, then dosed the ponds with a lethal amount. Groups that had been given low doses survived the lethal phase whereas unpolluted, control ponds did not. Researchers observed “community rescue,” where genetic changes avert population collapse in a lethal environment. In fact, glyphosate eventually became a fertilizer in resistant ponds as it is a significant source of phosphorus. Other studies, too, have noted that phosphorous loading is an overlooked impact of glyphosate contamination.    The resulting damage to genetic diversity causes concern. Andrew Gonzalez, Ph.D., says, “We observed significant loss of biodiversity in communities contaminated with glyphosate. This could have a profound impact on the proper functioning of ecosystems and lower the chance that they can adapt to new pollutants or stressors.'

Baby Bees’ Brain Growth Adversely Affected by Neonicotinoid Insecticides

 Baby Bees’ Brain Growth Adversely Affected by Neonicotinoid Insecticides

(Beyond Pesticides, March 6, 2020) 
This research, however, examines how exposure to the neonicotinoid imidacloprid, through consumption of contaminated nectar and pollen during the larval stage, affects bumblebees (Bombus terrestris audax). It finds that these exposures cause abnormal brain growth in some parts of the bees’ brains, and significantly impairs learning ability compared to bees who were not exposed....The brains of nearly 100 bees were examined, and the team found that an important part of the bee brain involved with learning — the mushroom body — was smaller in those exposed to the neonics. Smaller mushroom body volume is correlated with poorer performance in learning tasks. Bees fed with contaminated food in the larval stage show significantly impaired learning ability compared to those that are not.

Further, bee larvae have been shown to be vulnerable not only to a single pesticide, but also, to synergistic effects of the plethora of pesticides that may end up in the colony’s hive, plus the so-called “inert” ingredients in pesticide compounds. Researchers in one study noted, “One hundred and twenty-one different pesticides and metabolites were identified in the hive with an average of seven pesticides per pollen sample, including miticides, insecticides, fungicides, herbicides, and insect growth regulators.”

'The amount of pesticide residue present inside colonies following exposure appears to be an important measure for assessing the impact on a colony’s health in the future.”'

SNAP Comment: In my view, if it is affecting the development of bumblebee's brains, there is no reason it can't affect humans.

Report Finds Top Chemical Companies Making Billions Off Poisoning the Earth

(Beyond Pesticides, February 27, 2020) A new report finds that as birds and pollinators continue to decline, and chronic diseases remain on the rise, the global agrichemical industry is raking in billions of dollars from hazardous pesticides that contribute to these crises. A joint investigation from Unearthed and Public Eye finds that 35% of pesticide sales from the largest agrichemical corporations are made from the most toxic pesticides on the market

Longest Field Trials Show Organic Practices Yield Higher Returns than Chemical-Intensive Agriculture  (Beyond Pesticides, February 24, 2019)

 nearly 40-year research project are these:

  • after a five-year transition period, organic yields are competitive with conventional yields
  • in drought years, organic yields are as much as 40% higher than conventional yields
  • farm profits are 3–6 times higher for products from organically managed systems
  • organic management systems use 45% less energy than conventional, and release 40% fewer carbon emissions into the atmosphere
  • organic systems leach no toxic chemicals into waterways
  • organic systems build, rather than deplete, organic matter in soil, improving soil health

Experts Identify Fireflies as the Latest Victim of the Ongoing Insect Apocalypse

Experts Identify Fireflies as the Latest Victim of the Ongoing Insect Apocalypse  (Beyond Pesticides, February 19, 2020) 

'In an article published this month, “A Global Perspective on Firefly Extinction Threats,” experts are sounding the alarm over declines in fireflies attributed to habitat loss, light pollution, and indiscriminate pesticide use.

Pesticide use is particularly pernicious in the context of firefly ecology. While direct contact with pesticide sprays is a concern, exposure in soil and water represent greater hazards. This is because many firefly species lay their eggs in soil, and many spend the first years of their life in aquatic habitats like mangroves and other riparian vegetation (vegetation along the banks of waterways). Pesticides, like the neonicotinoid class of insecticides also implicated in pollinator declines, are known to drift once applied, and persist in soil and waterways.'

Major Manufacturer of Chlorpyrifos Drops Out of Market, But EPA Continues to Allow Use

Major Manufacturer of Chlorpyrifos Drops Out of Market, But EPA Continues to Allow Use

(Beyond Pesticides, February 12, 2020) 'Corteva, a company spun-off from DowDupont, will stop producing chlorpyrifos by the end of this year as a result of declining sales. Despite the move being in the interest of public health, the company is earning little praise from health advocates for what amounts to simply a shrewd financial decision.

At odds is the difference between halting production of chlorpyrifos and cancelling its EPA registration. While Corteva has the ability to voluntarily stop producing its own product, EPA registration permits other generic manufacturers to continue to producing the product. And, over the years, there would be nothing to stop Corteva from reintroducing “new” chlorpyrifos products back onto the market.

The removal of Corteva (DowDupont) from the chlorpyrifos marketplace is indicative of a pattern within the current administration that puts profit at all cost above the health of the American people, and American children in particular, according to advocates. Decisions regarding public health should not be determined by the dictates of the marketplace, but by the sound science in states like NY, CA, and HI, the EU and other countries are following for the benefit of their residents.
