I envision further developments that will reduce or eliminate the need for fertilizers. Higher yields will spare prairie lands and forests from cultivation. Human nutrition will be greatly improved. Vitamins, protectors against atherosclerosis and cancer antagonists will enrich the food we eat. Costs of food and products such as plastics will be lower.
Crops can be more resistant to drought and cool weather.
Less plowing will be required, saving topsoil. Each generation will be able to meet its needs without robbing those who come after. The arguments about genetically modified foods will likely continue, for we humans can never predict the future with certainty. Moreover, scientists can never prove a negative. We do know, however, that hungry people abound in the world and that our current agricultural practices are risky and are not sustainable.
