Tolik, the US population in 1940 was 132 million. It is now 322 million. During that time we lost 14% of our farmland and are currently losing about 1 million additional acres per year. In 1940 we had about 8 acres of farmland per person. Now it is about 2.8. The issue isn’t so much current capabilities, but rather the ongoing addition of about 3 million more people each year in conjunction with the loss of 1 million acres of farmland each year.
