I think they knew it wasn't going to be perfect because they knew or thought they had to roll it out fast. I think all in med research and health clinicians realized it's not ideal to do these things fast, but, they didn't have time because it was a historical pandemic, not seen in this generation.
Not being in the AG industry, I do have a question about Roundup. I and many obviously know what it is but I don't stay up on the regulations in AG. I suspect Roundup is still used? Not? If is, did they lock down on more stringent regulations? I'm out of that circle so don't know but curious as if it is managed differently now. Txs.
The issue with glyphosate is that contact through skin and breathing can cause cancer. Roundup the Monsanto trade name has a surfactant in it that is also an issue. Glyphosate is an endocrine disrupter. The thyroid is a part of the endocrine system. Glyphosate is easily found in the food chain. It also destroys proteins. The EU has banned it, though it is still used in Ukraine to a large extent though it is against the law as well. Top that off with that roundup is used in conjunction with gmo grain which destroys the intestines of pests. Go back to the 90s and look at photos/videos of the general population. The contrast is shocking. Obesity is a complex issue, but there are studies that do show gmo and glyphosate impact health and one area is in obesity. Roundup use exploded in popularity as it make farming so much easier. It's used in both corn and soybeans, but primarily soybeans which is the crop that is most directly used for human consumption. Corn is about 1/3 ethanol and a large amount goes to feeding livestock. Guarantee a test if done would show you have glyphosate in your body. Even organic crops are getting contaminated.
Glyphosate is still used in the US. Roundup like many vaccines is not protected and there are many generic versions which decreased Monsanto's profits. Monsanto was facing billions of dollars in lawsuits in Europe and the US so they sold the rights to the Roundup trade name to Bayer. Bayer is stopping the home use of Roundup this year and say they are changing it both in this market and ag, but aren't saying what they are putting in it basically yet. The EPA fights for glyphosate quite hard in contrast to the European version.
Basically in both the rolling out of farm chemicals and gmo hybrids, the companies (which are basically pharma) appeal to EPA for an "emergency label" for some big impending threatening calamity use that bypasses extensive testing. GMO's were not really testing.
Rest assured, the ag chemical/seed industry is in part to blame for the reduction in the bee population and obesity. European corn borers that used to cover our windshields are gone except in wheat country (borers aren't native). Monarchs began reducing when GMOs/Roundup and now have made a slight comeback with more non-gmo crops being used (the soybeans with weeds). Mosquitos are disappearing. Some are saying great, but this is a sign of a major problem.
The US Govt isn't going to help much with regulation, but the pocketbook is. Back in the 90s some started being concerned with reductions in earth worm populations in farm fields. It has been very detrimental. The use of insectide was the main issue. Now trying to preserve earthworm populations is generally mainstream.
