Food and Agriculture. In the United States, we are fortunate to have an abundant supply of food, and much of this is due to our agricultural technology. However, there are many concerns about our food source, including genetically modified crops, the use of more chemicals, and climate change. Provide at least two modern examples of how the United States has increased its food production. Using at least two scholarly sources, discuss how these changes have affected the environment, and what impact they have on food safety?
