Genetically modified foods are organisms that have had their DNA altered through genetic engineering, not natural breeding. This document discusses how GM foods could help address issues like increasing global population, crop diseases, and resource scarcity. It provides examples of GM crops like Bt brinjal, Bt corn, and golden rice but notes there is controversy over their impacts on antibiotic resistance, biodiversity, and health. The document is presented by Rysul Hasan Hredoy for an environmental studies course.
