I'm doing a presentation on successful urban ag projects for stakeholders in
St Petersburg, FL, and would love to hear from permaculturists who have
something going with such as:
successful community urban ag project (community gardens, etc)
successful urban farms
successful co-ops, CSAs, or other alternative economy approach to urban
farming
successful urban ag program in schools, universities, etc
I want to have permaculture well represented in this report and I know there
are some great projects out there. I know about some of them, but I'm sure,
not all of them.?

A great one is in Oakland, CA called Planting Justice. They'll come up in a
google search. Good luck!

Is Roundup Weedkiller A Brain-Damaging Neurotoxin? By Sayer Ji, Founder
A new study reveals a hitherto unknown mechanism behind how the world's
most popular GMO herbicide harms the brain.
Remarkably, despite Roundup® herbicide's widespread approval around the
world, the most basic mechanisms through which it exerts toxicity towards
non-target animal species (including humans) have yet to be adequately
characterized.
Concerned about Brazil's status as the largest global consumer of
pesticides since 2008, researchers sought to elucidate toxicologic effects
of these agrochemicals in humans.
Their new study, published in the journal Toxicology, provides a proposed
mechanism for the adverse neurological effects of Roundup® (a
glyphosate-based herbicide). It is has been observed that agrochemical
exposure can lead to, or accelerate, neurodegenerative disorders, such as
Parkinson's and Alzheimer's disease. However, lacking a mechanism of
action, such a link can more easily be written off as coincidental; which
is largely the position of the medical establishment, agricultural
industry, and its would-be regulators. The authors point out that,
"neurodegenerative conditions are frequently associated with glutamatergic
excitotoxicity and oxidative stress," which is why they decided to
investigate the subject further.
Titled, "Mechanisms underlying the neurotoxicity induced by
glyphosate-based herbicide in immature rat hippocampus: Involvement of
glutamate excitotoxicity,"[i] the paper tested the neurotoxicity of
Roundup® in the hippocampus of immature rats following acute exposure (30
minutes) and chronic (pregnancy and lactation) exposure.
The results found that acute exposure to Roundup® induces calcium influx
into neurons (primarily, by activating NMDA receptors and voltage-dependent
Ca2+ channels), leading to oxidative stress and neural cell death. They
also found that the herbicide affected the enzymes ERK and CaMKII, the
later of which is an enzyme whose dysregulation has been linked to
Alzheimer's disease.[ii] Additionally, acute exposure was observed to have
the following three effects:
Increase the amino acid glutamate into the junctions through which neurons
communicate (synaptic cleft), which, when released in excess levels, can
exert excitotoxic/neurotixc effects in neurons.
Decrease the neuroprotective antioxidant glutathione.
Increase 'brain rancidity,' i.e. lipoperoxidation, characterized by
excitotoxicity (over-stimulation of the neurons) and oxidative damage.
The summarization of their results, looking at the effects of both acute
and chronic exposure, were reported as follows:
"Taken together, these results demonstrated that Roundup® might lead to
excessive extracellular glutamate levels and consequently to glutamate
excitotoxicity and oxidative stress in rat hippocampus."
Roundup-induced glutamate excitotoxicity appears to share similar effects
to monosodium glutamate (MSG) and aspartame-linked excitotoxicity, and
indicating that anyone either prone to, or suffering from, a brain or
neurological condition involving increased oxidative stress and/or neuronal
excitotoxicity (pathological or excessive nerve cell stimulation) should be
even more wary to reduce exposure to this unfortunately ubiquitous
environmental and food contaminant.
The authors also pointed out that their study found maternal exposure to
Roundup® resulted in the offspring being exposed to the herbicide because
it crosses the placental barrier during gestation and/or it is passed to
them through the breast milk. They caution:
"Exposure to environmental toxicants during pregnancy and suckling periods
has the potential to affect embryo and fetal development."
This is not the first time that concerns have been raised about Roundup's
unique contraceptive and birth defect causing properties.
