How has human activity changed with the advent of iron tools? What have these changes led to?

Although iron is not the first metal that mankind has used in history, it is it that has had the greatest impact. Since iron is much stronger and more durable than bronze, it became easier for them to work the land (bronze tools broke often). This contributed to the development of new lands, the amount of supplies increased and began to give the remainder. All this influenced the stratification of society, the disappearance of the fiery way of life, and the emergence of rich and poor.
