How has people’s lives changed after the discovery of metal?

After the discovery of metals, agriculture became one of the main industries for most peoples. Iron axes and hoes greatly facilitated the cultivation of the land and agricultural work. All this led to an increase in the amount of food produced, and famine was less of a threat to communities. Neither stone nor bronze could resist iron, and people had the opportunity to make more advanced and durable tools and weapons. It became easier to hunt.
