I encourage you to read more on the science and research surrounding glyphosate, the active ingredient in RoundUp. There is little to no evidence that Glyohosate is harmful to humans, animals or the environment apart from the individual plant it is sprayed directly onto.
Science Based Medicine did a wonderful article on the subject and current scientific consensus here.
You can even google many different videos of people drinking fairly large quantities of glyphosate on camera.
The word “toxic” is not a particularly scientific or meaningful term in this case as every chemical compound has a toxicity level and therefore could be considered “toxic” including compounds like H2O.
I began my research on this weed with much of the same opinion as it seems you currently have on the subject, but after doing my due diligence and having an open mind to the current scientific research on the matter, I no longer believe that my concerns were rational given the current state of the science. I encourage you to take a honest and open minded look at the scientific research rather than what is on sites such as Natural News, which have a history of spreading false, misleading, and unscientific views and opinions on many topic such as glyphosate, vaccines, and homeopathy.
