"Agriculture not only gives riches to a nation, but the only riches she can call her own." -- Samuel Johnson, English writer (born September 18, 1709)
Did you know that America loses 1.2 MILLION acres of farmland each year? According to American Farmland Trust, most of this is the best and most productive farmland we have. Where we used to live in Niagara County, in NY, we would see this happening acre by acre, as the edges of farm fields were sold off where they fronted on a road, and houses were built as the lots sold. But, it's been going on for years, all over the country.
