Genetically modified crops

Glyphosate 3D balls.Image via Wikipedia GM canola is good for farmers because it is resistant to being sprayed by Roundup weedkiller. Otherwise known as glyphosphate it is made by Monsanto
By a strange coincidence, GM canola is also a product of Monsanto.

A review of the literature in 2000 concluded that "under present and expected conditions of new use, there is no potential for Roundup herbicide to pose a health risk to humans".[4] This review considered the likely effects experienced by the two groups most likely to have high exposures, herbicide applicators and children aged 1-6, noting the exposure in those subpopulations was not a health concern.[4] Glyphosate has an EPA Toxicity Class of III in 1993,[5] but more recent studies suggest that IV is appropriate for oral, dermal, and inhalation exposure.[4] It has been rated as class I (Severe) for eye irritation, however.[4]

Outside its intended use, glyphosate can be lethal. For example, with intentional poisonings there is approximately a 10% mortality for those ingesting glyphosate, compared to 70% for those ingesting paraquat.[6]

Laboratory toxicology studies suggest that other ingredients combined with glyphosate may have greater toxicity than glyphosate alone. For example, a study comparing glyphosate and Roundup found that Roundup had a greater effect on aromatase than glyphosate alone.[7]

So, you may consume GM canola without knowing it. That is the point.
If it is safe then why not shout it out from the roofs?
If people want to consume a product that has aborbed glyphosphate then let them know what they are consuming. Let the consumer make the choice.

I've just read what an apologist for GM canola is saying. That GM canola requires less Roundup than ordinary canola crops.
