Earth Be Different If Iron Didn T Exist?

How would earth be different if iron didn’t exist? What would we lose? how might it affect you?

If we didn’t have iron we wouldn’t have a large portion of the earth’s core. Without the earth’s core we would have less gravity and everything would be lighter and atrophy would happen to our muscle and bone density. If there is less gravity the would drift away from earth leaving us with chaotic weather and chaotic tides. The core also creates a shield which helps with a variety of of things not happening. Some examples are auroras would happen all over the planet, we would lose control of our power grid and electronics, extra radiation exposure and to the loss of the atmosphere altogether. Without iron everything living on earth would die reason being is that every living thing needs iron to survive and grow. A lot of things we have today are made of iron such as frames of glasses to vehicles,to the buildings we live and work in.So without iron earth there would be crazy weather with crazy tides and nothing would be living on it.
About sixty percent of a car is made up of steel. So if we didn’t have steel there would be no cars. The roofs to some of our houses would be gone since there are steel roofs wich last much longer than a standard wooden roof. There would also be less guns being manufactured because they are made of steel. It’s pretty crazy if there weren’t any guns. Then we would probably only have chemical warfare If we some how learned to survive without iron what i’m saying is steel is important but you can’t have it without iron. Also without iron we wouldn’t have DNA or the simple ability to breath because iron is a key ingredient of making DNA and Hemoglobin which is an iron rich protein in red blood cells. It helps red blood cells carry oxygen from the lungs to the rest of the
