Until recently, the fight over Roundup has mostly focused on its active ingredient, glyphosate. But mounting evidence, including one study published in February, shows it’s not only glyphosate that’s dangerous, but also chemicals listed as “inert ingredients” in some formulations of Roundup and other glyphosate-based weed killers. Though they have been in herbicides — and our environment — for decades, these chemicals have evaded scientific scrutiny and regulation in large part because the companies that make and use them have concealed their identity as trade secrets.

Remember the infamous interview where the Monsanto lobbyist, Patrick Moore, claimed that Roundup was safe to drink but then refused to actually drink any? May be he knew about this. And no your argument about coal doesn't hold water here. There's really no point to claiming that something's safe because other things are more dangerous. In addition, Roundup is far more dangerous than radioactivity from coal. Then the point about Roundup users tasting it? You don't think that they may inhale it while spraying it from backpacks, tractors, and mobile spray tanks, do you?
Let's start with you suggesting an alternative. Of all the chemicals farmers use to control weeds on their farms, round-up is far and away the safest. If you are truly concerned for the farmers out there applying it, what is their alternative? They either don't spray anything to control weeds, or they use MORE dangerous chemicals than round-up.
Let's also have some perspective on 'danger' here. I'm having trouble pulling up the human LD50 for round-up. That's likely because they lack test cases of anybody actually dying that way to reference. Regardless, let's list the ld50 for round up and some other substances, shall we?
LD50 in rats:
Vitamin A 2000mg/kg
Table Salt 3000mg/kg
So when sampling Aspirin, Salt,Vitamin A, Alcohol, Sugar and Round-up, only TWO of those substances are less toxic than round-up. Maybe a little less fear and uncertainty is warranted. Particularly given that nobody is advocating incorporating glyphosate into our diets. We are talking about glyphosate being used to control weeds in crops, and in such a way that the amount that ever traces it's way off the farm is minuscule.
Taking a case of 'extreme' glyophsate concentrations from the first alarmist source I could find cited 9mg/kg of glyphosate in Norwegian Soy GE crops. Takign the average daily food intake for people at 2kg and assuming we force feed a subject exclusively this 'extreme' contaminated soy bean, we get a daily intake of 18mg of glyphosate. Now, that's an utterly extreme case, and not realistic, but let's examine that worst of worst cases closer. The average human weighs in at 80kg and it's inexact, but the best we've got to say the LD50 is like rats at 5000mg/kg, meaning that a lethal dose for our average subject is 400,000mg. Working out the math our extremely contaminated GE soybeans are inflicting 0.000045% of a lethal dose.
Let's give more reference, the average daily salt intake for our regular joe we just victimized is 3400mg. Again weighing in at 80kg and with a LD50 for salt at 3000mg/kg we have a lethal dose of salt weighing 240,000mg. Doing the math again, our victim regularly consumes 0.014% of a lethal dose of salt daily all by themselves.
The difference between medicine and poison is dosage, and in the case of gylphosate our food is nowhere near the dangerous stage all the fear mongers want to promote.
