Fact-Check Article: "GMO foods don't contain large amounts of glyphosate"

What We Know

Genetically modified organisms (GMOs), particularly those engineered to be glyphosate-tolerant, are widely used in agriculture. According to a study on GM crop use from 1996 to 2020, glyphosate is the most commonly developed trait in GM crops, allowing farmers to apply glyphosate herbicides without harming the crops. This has led to significant reductions in overall pesticide use, with a noted decrease in the environmental impact associated with herbicide application.

However, the presence of glyphosate residues in GMO foods has been documented. A 2023 report indicates that measurable quantities of glyphosate are detected in some GMO products, suggesting that while GMOs may not contain "large amounts" of glyphosate, they are not entirely free from it. Additionally, a 2015 review highlighted that glyphosate-tolerant crops can accumulate glyphosate residues, raising concerns about the levels that may be passed on to consumers.

Furthermore, it is noted that over 80% of GM crops globally are engineered to tolerate glyphosate, which indicates a strong correlation between GMO cultivation and glyphosate application (Detox Project).

Analysis

The claim that "GMO foods don't contain large amounts of glyphosate" is nuanced. On one hand, the assertion could be interpreted to mean that GMO foods are not saturated with glyphosate, which aligns with findings that suggest glyphosate levels in food products are generally below established safety thresholds (GMO Answers). However, the existence of glyphosate residues in GMO foods is well-documented, and the levels can vary depending on several factors, including agricultural practices and regulatory standards.

The reliability of the sources is mixed. The 2023 report from a reputable pediatric journal provides a contemporary overview of glyphosate residues in GMO foods, while the 2015 review raises valid concerns about the methodology of industry studies, suggesting that they may not adequately address glyphosate residue levels. This indicates a potential bias in industry-sponsored research, which could downplay the presence of glyphosate in GMOs.

Moreover, the study on GM crop use presents a comprehensive analysis of pesticide use over time, but it primarily focuses on the environmental impacts rather than specific residue levels in food products. This may limit its applicability to the claim being evaluated.

Conclusion

The claim that "GMO foods don't contain large amounts of glyphosate" is Partially True. While it is accurate that GMO foods may not contain "large amounts" of glyphosate in the sense that they are generally below safety thresholds, the presence of measurable glyphosate residues in these foods cannot be denied. The variability in residue levels and the potential for accumulation in certain crops complicate the assertion. Therefore, while the claim has some basis in fact, it does not fully capture the complexity of glyphosate presence in GMO foods.

Fact Check: There is no question Mark Carney is a brilliant business man and has a very impressive resume. But does he give a shit about you, and for that matter other Canadians? I didn't know anything about Mark Carney a couple of weeks ago and yesterday, I decided to do a little research project. This is what I discovered with about 1 hour of research. Lets take a bit of a dive in… Mark Carney is the UN special envoy on climate change pushing governments around the world to adopt “clean energy”. A great position, no? Interestingly, right up until he entered the Liberal leadership race, he also conveniently sat on the board of Brookfield Asset Management at the same time as he sat in this position with the UN. Brookfield owns $1 trillion in assets under management and many of their portfolios are across renewable power & infrastructure. Hmm, sounds a little conflicty? He has directly profited off of the shutting down and blocking of fossil fuel projects in Canada which he advised Canada to do (and other nations) while making sure so called “green energy” options are pushed and approved, which line his own pockets with green. One of Mark's acts as Chair of the board was to move the head office of Brookfield from Toronto to New York, because of the impending tariff war. Sounds like he has a lot of faith in his ability to put Canada first...and then he lied about the whole situation claiming that he was not chair when Brookfield moved. Maybe true, but he approved the move and voted for it at the first hint of tariffs from Trump, while he was still chair… Let’s look further at Mark’s role with Brookfield though. While he was doing all this “good work”, or rather making western governments do all this good work while he profits off of them, he was also directing Brookfield to act completely contrary environmentally when it suits the firm and their shareholders. While Brookfield manages green companies, they also acquire and invest in “dirty” fossil fuel projects and “carbon releasing” in other parts of the world. “One of Brookfield's collection of assets was 267,000 hectares in Brazil. producing soybeans, sugar, corn and cattle. between 2012 and 2021 Brookfield's subsidiaries deforested around 9,000 hectares on eight large farms in the Cerrado region of Brazil, a vast area bordering the Amazon rainforest. The report estimates that 600,000 tonnes of CO2 was emitted by deforesting these areas, the equivalent of 1.2 million flights from London to New York. A spokesperson for Brookfield said: "Brookfield made limited investments in Brazil's agriculture sector during the last decade. The decision to sell these businesses was taken several years ago because the fund they were held in was reaching the end of its life, and we therefore had an obligation to return capital to investors." Global Witness claims that this decision to sell clashes with public statements subsequently made by Mr. Carney as a global leader on climate policy, which call upon companies not to sell off climate-damaging assets, but to hold onto them and either clean them up or close them down”. - Ben King, BBC 15, Dec, 2022 They cut 9000 hectares of prime forest on the border of the Amazon to expand their GMO farming operations. Wow! How about the $16 billion acquisition of Inter Pipeline by Brookfield”? An oil pipeline, yes. Just two of the many "CO2 emitting" actions that Mark Carney has directed Brookfield on as Chair to the Board while he pushes green energy where it benefits his own books… A 2023 report on Brookfield by “Private Equity Climate Risks” paint a pretty bleak picture. "The combined current fossil fuel investments of Brookfield and Oaktree emit an estimated 159 million metric tons (mt) of CO2 equivalent (CO2e) annually. This is an order of magnitude more than the 11.8 million mt CO2e disclosed in Brookfield’s sustainability reports". So… will Carney be good for Canada? Well all of the above makes me think he is a wolf in sheep's clothing and let’s keep in mind he has been a close financial advisor to Trudeau since 2020. All of the great results of Trudeau’s tenure are the direct result of Carney. Doubling of house prices Record inflation Doubling of Canadians in the line of the food bank Our now crippling national debt and $60 billion deficit One of the biggest red flags for me is that Mark refuses to disclose his own personal financial situation. A guy who just a couple of months ago sat on 20 different corporate boards, including many American companies, promises he has a lot to gain by becoming PM. He is an ultra elite globalist who is 100% a part of the decisions that have led to Canada’s downfall and left us so vulnerable and if he remains as PM for any length of time, I feel Canada may end up bankrupt. The media will tell you that Mark is the guy to take on Trump, but the truth is not hard to uncover if you just do a little digging. Centrum
