Marketed since 1974, Roundup is a herbicide that includes glyphosate, which Monsanto determined could be used in its herbicides in 1970.
Since 1970s, the frequency of use of glyphosate-based herbicides has jumped 10,000 percent. Moreover, each year farmers, commercial nurseries, gardeners and groundskeepers of parks and golf courses have used about 250 million pounds of glyphosate.
Scientific studies in which normal human lymphocytes are exposed to Roundup in a test tube have shown damage to DNA as early as 1998. Dr. Fernando Manas, a biologist at the National University of Rio Cuarto in Argentina, discovered evidence of DNA damage after studying people who were employed in the soy industry and who were exposed to pesticides that used glyphosate. A study performed by the Pontifical Catholic University in Quito, Ecuador, by residents of northern Ecuador exposed to Roundup was found to have developed various health issues including abdominal pain, vomiting, fever, heart palpitations, blurred vision, insomnia, numbness and headaches as well as DNA damage.
The National Scientific Research Center and the University of Pierre and Marie Curie in France discovered in a study performed in 2004 that Roundup caused changes in the cell division of sea urchin embryos and the scientists found a direct link to the errors and the development of cancer due to the cumulative amounts of Roundup.
Moreover, the International Agency for Research on Cancer reported in March 2015 that exposure to Roundup can cause cancer. The report was based on studies that were performed since 2001 on the effects of glyphosate on agricultural workers. The study discovered that the rate of workers with non-Hodgkin lymphoma was higher in those exposed to Roundup than those who did not.
