The benefits and risks of the scientific method of genetically modifying crop species
Since the emergence of agriculture over 10,000 years ago, humans have been altering the genomes of the crops they produce in order to increase the crop quality in many ways, with fruit size and palatability being two obvious examples. Whether this occurred incidentally through the techniques used to cultivate the plants or intentionally through artificial selection, humans have created strains of domesticated plants that, through the exaggeration of already present traits, have become grossly distinct from their wild ancestors and relatives.
More modern techniques of plant breeding offered the ability to introduce new traits to a crop by crossing individuals

This is especially true for technologies that affect our food supply. It is important when evaluating the threat of such risks to distinguish the difference between actual potential risks and scare-stories spread by misinformation, misinterpretation, or sensationalism. As such, in my summary of the benefits and risks of genetically modifying crop species I will ignore those risks and worries that have been proven to be …show more content…
The latter benefit is due being tightly bound by the soil and then being degradable by soil bacteria, so fields sprayed with the glyphosphate are safe for use in crop rotation and pose no threat to local wildlife in terms of leaching. The herbicide interferes with the shikimate pathway, which is necessary for the synthesis of aromatic amino acids phenylalanine, tyrosine, and tryptophan. These are known as essential amino acids because animals lack the shikimate pathway and so must ingest them, which is also why glyphosphate is toxic to plants but has no effect on animals. A strain of A. tumefaciens was found to have a variant of the EPSPS enzyme (from the shikimate pathway) that is resistant to inhibition by glyphosphate citation needed. The gene encoding this enzyme has been introduced to many crops, with the first being soybean, and the result was so successful that now at least 90% of all GM crops being grown worldwide carry glyphosphate
