PARIS GREEN is described as highly toxic emerald-green crystalline. It was used in America and elsewhere as an insecticide for produce, such as apples, around 1900, where it was blended with lead arsenate. It was also used for rodent control and green paint pigment. Now, the old tin cans are collectible as antiques. It was considered back then to be perfectly safe if used as directed, probably marketed to farmers as a wonder product. Makes me wonder how the crop agricultural products in use today will be viewed a 100 years from now.
Glyphosate, the main ingredient in the herbicide Roundup, is now considered a carcinogen by Denmark’s Working Environment Authority:
“When we see that other mammals get cancer from glyphosate, we must assume that people who are exposed to the substance can also develop cancer,” says Philippe Grandjean, professor of environmental medicine at the University of Southern Denmark.
And according to Natural News, DNA from GMOs can pass directly into humans, study confirms:
(NaturalNews) The idea that DNA from genetically modified organisms (GMOs) is broken down in the digestive tract and rendered innocuous, a common industry claim, is patently false. A recent study published in the scientific journal <PUBLIC LIBRARY OF SCIENCE> PLOS ONE found that large, meal-derived DNA fragments from GMOs are fully capable of transferring their genes directly into the bloodstream, deconstructing the myth that transgenic foods act on the body in the same way as natural foods.
The article goes on to say:
The presence of transgenic genes in the small intestine was also found to affect the composition of beneficial bacteria, which are responsible for protecting the gut against foreign invaders and helping the body absorb nutrients from food…
None of this is really all that surprising, of course, as the biological activities behind how GMOs are processed by the human body have never been legitimately studied. Biotechnology companies have always just claimed that GMOs are the same as real food, without any evidence to back this up, and this has been enough for the government to keep them on the market for nearly 20 years.
We are somewhat helpless as individuals to change the growing tide of new GMO crops and number of highly toxic pesticides in the world. What we can do to make individual choices about what we eat and where we buy our food.
And, to think that once upon a time green paint literally killed people. Eventually, the use of this pigment was abandoned when it became generally known that people who wore clothes dyed with the substance tended to die early. To this day the French avoid making green theater costumes.
