Iron

Iron smelting did not begin untill the Europeans arived.

Why does Iron matter: iron matters because we need houses, and if we dont have houses and there was a tornado or it hailed we would all be injerd and living under drapes.

How does it effect the world: Iron effects the world because if we did not have iron we would not have sky scrapers and weapons for the military. Also if we did not have iron in the old days we would not have armor and weapons for knights.
