Glyphosate doesn't last in soil though, it's broken down in a few days by soil bacteria.

I have heard this too, but then how is it showing up in people later on?

  It gets into plants and animals during those days https://vancouversun.com/news/local-news/the-herbicide-glyphosate-persists-in-wild-edible-plants-b-c-study https://vancouversun.com/news/local-news/the-herbicide-glyph...

Doesn’t mean that it doesn't last elsewhere, studies in BC have shown that is persists in plants that are sprayed but don’t die for at least a year https://vancouversun.com/news/local-news/the-herbicide-glyphosate-persists-in-wild-edible-plants-b-c-study https://vancouversun.com/news/local-news/the-herbicide-glyph... Which makes the practice above of spraying replanted forests so “the good trees grow faster” even more abhorrent

  > the good trees grow faster They replant with round-up ready pine, so they spray to kill aspen which is a firebreak species, and grow massive pine stands which are the opposite. It's the major reason for the massive forest fires we've had lately (and thus the massive flooding).

    the more i learn about it the worse it gets :(

Do you have a source for that? I thought the half-life in soil was 90 days. Certainly would be perplexing as to how various Roundup products work for months to a year.

  The long-lasting Roundup products contain other active ingredients in addition to glyphosate.

    It seems regular Roundup has multiple active ingredients these days.

Let's not forget adjuvants.

If it show up in your urine, it mean it lasted too long. It is also a powerful chelating agent (make you lose minerals) is another concern for humans. "Although the chelating properties are well known, this potential additional environmental risk was never adequately considered in the regulatory risk assessment (EFSA 2015a, 2015b)." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5823954/#:~:text=Glyphosate%20is%20also%20known%20as,(Komives%20and%20Schr%C3%B6der%202016) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5823954/#:~:tex....

"a few days" is the lower end. From wikipedia: >The half-life of glyphosate in soil ranges between 2 and 197 days; a typical field half-life of 47 days has been suggested. Soil and climate conditions affect glyphosate's persistence in soil. The median half-life of glyphosate in water varies from a few to 91 days.[57] At a site in Texas, half-life was as little as three days. A site in Iowa had a half-life of 141.9 days
