Creating new farming technologies could also help solve world hunger. If food can be grown in large hydroponic farms, for example, there would less strain put on traditional soil farms. Farmers in poorer countries could be trained to rotate their crops in order to keep the soil healthier season after season. Better seeds with higher yields or resistance to insect or weather damage could help farmers grow more usable crops on the same amount of arable land. A renewed emphasis on agriculture as a career could also encourage more young people to start their own farms and produce more food for others.
