Corn has been grown by humans for approximately 10,000 years, and its genetics have been heavily modified through breeding and mutation to improve its utility as a crop over this very long period. The modern technique of transgenesis has been used to further improve the agronomic characteristics of corn over the last two decades. Transgenesis has become synonymous with the term “genetically modified” (GM) over this time period, but it is really a misnomer. So all corn on the planet has been genetically modified by human activities, but not all corn has transgenes inserted by the modern technique of transgenesis.
QIs it true that all corn on the planet is already genetically modified?

Can GM foods be sustainable forever? If so, what type of steps do we have to take to keep them sustainable?

GMOs are crops - and like any other version of the same crop, where you grow them and how you grow them is far more important than whether they are GMOs. No known system of agriculture can promise that it is sustainable forever; much agricultural research is being devoted to improving the sustainability of agriculture. In this regard, it appears likely that using GM technologies may improve sustainability of a particular crop cultured in a specific manner and place. Other... Read More

Your question is being asked about many things that surround pregnant woman. Recently, studies have shown that many different things can effect pregnancy. Chemicals in water, air, soil, many medications, infections and chronic diseases, poor blood sugar control, tobacco exposure, and even mental and physical stress all carry risk. What happens to the mother, happens to the baby. At risk is not only the baby’s immediate growth and development, but also risk for chronic diseases in later... Read More

In order to answer this question, it is important to first be clear about what a GMO/GMO farm is and secondly to discuss the complex issues relating to herbicide and pesticide use. What is a GMO/GMO farm? It is assumed that this question refers to genetically modified crops. GM crop technology has been widely used since the mid-1990s and in 2016 were planted on about 178 million hectares worldwide. The main GMO traits convey: Tolerance to specific herbicides (notably to glyphosate) in maize... Read More
