According to that Report's Summary, glyphosate—Roundup—Monsanto are synonymous with the number one selling herbicide used in genetically modified crop agriculture, even though glyphosate is manufactured by many companies in other countries.
The World Health Organization's IARC (International Agency for Research on Cancer) classified glyphosate as probable carcinogen [Group 2A] in 2015! How come it took so long? I find myself asking.The herbicidal action of glyphosate is primarily due to its capacity to block the production of essential amino acids in plants and some microorganisms through a pathway called "shikimate", which is present only in plants. Thus it was sold as 'safe' for animals and humans. 
According to the report, many deaths have resulted, especially in Asia. Unintentional cases of poisonings among users and bystanders have been reported resulting in severe chemical burns and respiratory problems.
Aerial spraying on crops can precipitate both acute and chronic health problems. Some acute health problems associated with glyphosate poisoning include:
As someone who was in practice as a consulting natural nutritionist, I came to realize that people who ate processed foods often suffered with gastric and/or digestive problems that resolved themselves once they switched to an organically-grown diet. Children on the Autism Spectrum also experience great relief when their diet is devoid of glyphosate residues and other chemicals.Abdominal pain, gastrointestinal infections, itchy or burning skin, skin infections (particularly prevalent in children), blisters, burning or weeping eyes, blurred vision, conjunctivitis, headaches, fever, rapid heartbeat, palpitations, raised blood pressure, dizziness, chest pains, numbness, insomnia, depression, debilitation, difficulty in breathing, respiratory infections, dry cough, sore throat, and unpleasant taste in the mouth.
Less common effects reported include balance disorder, reduced cognitive capacity, seizures, impaired vision, smell, hearing and taste, drop in blood pressure, twitches and tics, muscle paralysis, peripheral neuropathy, loss of gross and fine motor skills, excessive sweating, and severe fatigue. 
Long-term toxicity effects of glyphosate can include:
On top of all the above,[interference] with numerous mammalian organs and biochemical pathways, including inhibition of numerous enzymes, metabolic disturbances and oxidative stress leading to excessive membrane lipid peroxidation, and cell and tissue damage. Genotoxicity and endocrine disruption also lead to chronic health and developmental effects.
The IARC monograph on glyphosate, published in 2015, concludes that "there is limited evidence in humans for carcinogenicity of glyphosate" and "there is sufficient evidence in experimental animals for the carcinogenicity of glyphosate". 
As an aside, please note that during the fall Halloween and Harvest seasons, many farms offer what are called "corn field mazes" for children to enjoy finding their way through a labyrinth of cornstalks.Doctors in Argentina have reported a dramatic upsurge in long-term effects in areas where genetically modified soy crops are aerial sprayed with glyphosate. They include cancer, infertility, pregnancy problems, birth defects, and respiratory diseases. 
However, since most corn in the USA is genetically modified and sprayed inordinately with Roundup as part of the GMO seed contract farmers are forced to sign when they purchase GMO seeds, there possibly could be a hidden health threat to kids due to herbicide residue left on cornstalks. That ought to be taken into consideration by parents who have children with asthma or other respiratory allergies. If you're not sure about what I've just written, maybe it would be advisable to have an EpiPen on hand—just in case. Glyphosate is a very serious chemical that can cause serious harm.
Glyphosate, according to the Report, can cause endocrine disruption, reproductive and developmental problems, neurological and immune issues. It has equally devastating effects upon the environment, e.g., aquatic effects, soil and plant health, earthworms and beneficial insects (Monarch butterflies and bees come to mind), birds and other animals, including livestock and domestic animals. Several epidemiological studies have linked exposure to glyphosate with non-Hodgkin's lymphoma, hairy cell leukaemia, multiple myeloma, and DNA damage. 
Low concentrations of glyphosate can damage the liver, kidneys, skin cells and causes ageing and potentially cancer. 
Glyphosate can be found under numerous trade names, which can be read at pages 7 and 8 of the Report, which I encourage everyone to become familiar with so as not to be misinformed about any lawn or agricultural products you may purchase.
So how prevalent is Roundup use? According to the Report, its use has increased fifteen-fold since the introduction of GM Roundup Ready crops in 1996!
Here's what most folks don't know about glyphosate and should:
Several countries have restrictions and/or bans on the use of glyphosate, whereas in the USA, it's used like water on crops!It is also used for pre-harvest desiccation of cotton, cereals, peas, beans, and other crops, resulting in elevated residues in food and animal fodder from these crops. Germany has prohibited pre-harvest desiccation since May 2014 (Benbrook 2016). In the process known as hormesis, glyphosate at sublethal levels can actually stimulate plant growth and yield in older plants (Belz & Duke 2014). The sodium salt (e.g. Quotamaster) is used as a growth regulator on sugar cane—to hasten ripening, enhance sugar content, and promote earlier harvesting—and on peanuts. 
Glyphosate residues have been found in humans in their breast milk, blood and urine. One place where one would not expect to find glyphosate residues is in vaccines. Well, it's been confirmed in vaccines. See my article Another Vaccine "Bombshell" Glyphosate - Think Monsanto's Roundup - Confirmed in Most Vaccines.
Interestingly, researchers have found that glyphosate can predispose crops to certain diseases! How cost-effective is that? According to the 2009 research of Johal and Huber:
Personally, I'd like to see Monsanto be held accountable financially for crimes against the environment (ecocide) and humanity. However, with the Bayer Monsanto buyout, I don't expect much relief from toxic chemicals. What I think will happen is the Monsanto brand will be phased out very soon, but humankind still will have to deal with multiple toxic chemicals Bayer will produce and sell, including glyphosate, I offer. Bringing class action lawsuits against chemical companies may send the message; see the Monsanto Roundup Lawsuit in the Resources below.
However, it will be up to consumers and farmers, in particular, to make their concerns and priorities known about saving the planet and humankind from toxic chemicals in food, water and the air, if we are to survive toxic chemicals and their currently unavoidable poisonings.
