This article basically explained the definition of GMO's which are a genetically modified organism. Some of the new material I learned is that genetically modified crops are made to be herbicide tolerant which has made it weed resistant. As a result sometimes as much as four time more herbicide has to be sprayed. What I found the most interesting that in 2015 glyphosate, an ingredient used in Round Up or herbicide, is a probable human carcinogen.
