The concept of Money

With the world economy currently only being held together by tiny threads I started to think about the whole concept of money.

What is money? Well the Oxford dictionary describes it as: 

noun

[mass noun]

• a current medium of exchange in the form of coins and banknotes; coins and banknotes collectively:

  I counted the money before putting it in my wallethe borrowed money to modernize the shop
  However, I personally believe that money is the root of all evil. It plays with peoples emotions and ambitions without even trying. It can single handedly tear a family apart. Whole nations have been turned upside down because of it. 
  Just try to imagine a world without money...
