Consequently, modern plant improvement specialists know exactly which genes they are adding to a particular plant and why. Many citizens of underdeveloped countries could benefit from crops modified in a way that adds to their staples' essential vitamins and nutrients. In addition, as scientists learn more about how plants defend themselves against nature's stresses, GMOs can be created to increase their resistance to those stresses and disease. Thus, more plants would survive in adverse situations. The four chief concerns evident in public opinion include the potential for allergenicity, the environmental risks of gene transfer, the loss of gene diversity and biodiversity, and the economic threat to herbicide and pesticide companies.
People fear that scientists are creating toxic and allergenic foods.
Furthermore, researchers can predict the probability of whether a new protein will cause an allergic reaction. Genes don't hop from one plant to another. Thirdly, the public worries that increasing the use of GMOs will cause a decline in gene diversity and biodiversity. However, not much gene diversity exists in plants already. In addition, a small change in some crops will not cause the animal populations higher on the food chain to disappear.
