One of the principal speakers at the conference was Prof. Philip Landrigan, a pediatrician at Mount Sinai Hospital in New York, who noted that many countries worldwide have reported a sharp rise in recent years in the prevalence of development disorders such as autism and ADD. This rise cannot be attributed solely to genetic factors or to higher rates of diagnosis, he said, and today, even researchers who once thought environmental factors could explain only a small fraction of the increased incidence of autism, for instance, have been convinced that it accounts for at least 25 percent of the rise.
Bryan Jasons wrote:The idea that we've been exposed to toxins for generations and so it's probably not a big deal, doesn't take into consideration trans-generational and epigentic effects. Barbara McClintock showed that in Maize the expression of genes would change depending on the environment it was grown in..
Bryan Jasons wrote:"How do these companies get to poison us and our children?" It's probably because people are assumed innocent until proven guilty, and so these companies simply deny that there is evidence of harm until it's not deniable and people are dead. Caution is relatively unprofitable I guess? If the choice is protecting long term health vs. having jobs, people almost always choose to have jobs.
Michael Cox wrote:I think part of our roll when designing permaculture systems is to design them to clean and improve the environment. Water coming into our land should leave cleaner than it comes in, trees should slow wind and trap particulates, increased soil carbon content and biodiversity will help bring soil contaminants into balance.
Michael Cox wrote:Changing the external sources is very difficult in a reasonable time scale, but changing local conditions is more achievable than most people realise. AS more people start cultivating using permaculture principals the overall environment will incrementally improve.

Bryan Jasons wrote:There are some experiments showing that various neurotransmitters and hormones can cause/contribute to, or block, excitotoxicity, which kills nerve cells and causes behavioral, learning, and motor impairments. In the animal studies, early life excitotoxic lesions in the brain can make rats run around in circles or develop states similar to schizophrenia. It's a pretty general thing, so I don't know all the details.. but it seems like children are increasingly excessively stressed, stimulated, compulsive, etc. and it might not just be the abundance of stimulation from phones and such, but an increased susceptibility to develop, or have already, pathological changes in their nervous systems. This comparison is speculative, but interesting to me..

Toxins and pollution, food choices, vaccines and medicines all have effects on the community and "our" symptoms are secondary or tertiary effects.
Does our body have an organism that filters a certain pollutant? Then it won't affect us. Do we have one that mines/concentrates one? Then we are extra susceptible to that toxins effects.
Is it a blessing or a curse? Only time will tell...
