Let’s start with the science, which of course we all love and accept. Scientists and engineers manipulate GM crops by inserting or deleting genes in various plants, enabling those plants to resist drought, resist pesticides, grow in non-native environments, or produce more stuff (like cotton). Scientists do this with genes from things like bacteria and even fireflies or fish (note: this inter-species genetic sharing can actually occur naturally, but it’s not common). But based only on our knowledge of objective science, we’re already forced to weigh the positives and negatives of GMOs. Recalling a gag from one of my favorite Simpsons episodes:
