Sustaining life on earth: Think of iron as the crucial link in ensuring everything functions as it is supposed to, from human beings to other essential aspects such as cars and the many gadgets that make life easier and more convenient. Apart from sustaining plants, iron plays a vital role in the human body as it carries oxygen in the blood giving it the red colour. It may not be obvious, but most kitchen gadgets and utensils are made with stainless steel which is a product of iron. Iron is also not a stranger in the medical world as it is used to make some medicines such as ferrous sulfate. In simple terms, life would never be the same without iron.
Construction and manufacturing industries: Iron is versatile; its uses are limitless as it can be manipulated to any form depending on what is being made. Iron is used to make steel which in return is used to 
create dozens of items from automobiles, furniture, the rods used to reinforce concrete, locomotives, bridges, electricity pylons and even simple things such as paper clips. The list of items that are made using iron is endless.
In medicine: Iron is an essential aspect of human life. Iron deficiency could lead to conditions such as being anaemic. Iron also exists as a dietary supplement and is prescribed to people who have anaemia to assist the body in the production of red blood cells. The supplements can be in different forms; tablets, capsules or in liquid form. There are different types of iron supplements, but all of them do the same job. Iron is also found in foods such as red meats, fish and poultry.
