The World of Genetically Modified Organisms (GMOs)
A genetically modified organism, or GMO, is a product of advanced sciences such as bioengineering, genetic engineering, and transgenic technology. Through these processes, the genetic material of plants, animals, or microorganisms is altered in a laboratory setting.
The breakthrough in GMO technology occurred in 1973 when scientists Herbert Boyer and Stanley Cohen successfully engineered the first genetically modified organism. This involved cutting out a specific gene from one organism and inserting it into another, giving rise to organisms with traits not naturally occurring.
The development of GMOs raised concerns about potential consequences for human health and the environment. In response, the Asilomar Conference of 1975 brought together experts to establish guidelines ensuring safety and containment in genetic engineering experiments. These guidelines were designed to evolve with advancing scientific knowledge.
GMOs have become increasingly prevalent in our daily lives, contributing to higher plant yields, reduced pesticide use, and purportedly addressing climate change concerns. However, understanding the choices we make regarding the consumption of organic or non-organic foods is essential in navigating the impact of genetic modification on our diets.
The Prevalence of GMOs
The prevalence of genetically altered organisms stands as one of the most pressing environmental challenges in the 21st century. The ubiquity of GMOs may not be immediately apparent, especially when considering everyday essentials such as cotton and corn-based products like corn syrup. Astonishingly, up to 92% of corn and 94% of cotton are genetically engineered, underscoring the pervasive influence of GMOs in our daily lives. The sheer scale of the population affected by this relatively new science raises concerns about the potential impacts on human, ecological, and environmental health.
Top 4 GMO Foods
