Americans created farmland out of forests, swamp and deserts. They built dams and canals for irrigation. They produced the world's most widespread and inexpensive agriculture.
Today the population is growing by leaps and bounds by natural and immigration means. Yet many hundreds of thousands of acres of productive land is going out of use. At the same time we have chronic water shortages, particularly west of the Mississippi River.
This has not stopped environmentalists from doing what it is they have been organized to do. They stop irrigation wherever they can, to save threatened species of fish and other organisms they see on the same level with human needs.
The upshot? We are taking too much productive farmland away from our food supplies. As well as making food we do have more expensive.
What is more, the trend continues in the face of current economic hardship.
