Americans in the past created farmland out of forests, swamp and deserts.They produced the world's most widespread and inexpensive agriculture. They built dams and canals.
Today, the population is growing by natural and immigration means. Yet many hundreds of thousands of acres of productive land is pushed out of use. At the same time we have chronic water shortages, particularly west of the Mississippi River.
We are also taking too much productive farmland away from food supplies. As well as making food we do have more expensive.
