The use of chemical fertilizer/drugs/antibiotics have contaminated our ecosystem and compromised metabolic pathway used by microbial communities and plants (shikimate pathway) for the biosynthesis of essential amino acids that cannot be made by the human body.
These chemicals move throughout our ecosystem, making their way into groundwater and our supply of drinking water, traveling down streams and rivers, reaching the ocean, and eventually winding up in the food on our plates, and ultimately in our bloodstreams.
