Today we finished watching Jarod Diamond's explanation of the roots of inequality. Gwar is 9,000 years old, which is 2,500 years after Draa. A few hundred people lived there instead of 40-50 people. Advanced houses were made with plaster made from limestone heated to 1000 degrees. When an area was over farmed a group could move on the same line of latitude and not have to change their way of living. Before the 16th century there was no wheat or cows in North America. Today there are over 100,000,000 cows and bulls in the United States today. 20,000,000 tons of wheat are consumed every year in the United States.
