Short Note on Necessity Is The Mother Of Invention For Students

  Necessity is the mother of invention

We could not get everything from nature.  So, we invented things, when men were hunters, they had to invent tricks for catching wild animals,  When they needed fire, they invented it. When they  wanted to cross the sea, they invented boats and ships. When they had to fight wild animal ,

 they invented weapons.  They wanted to spread news and knowledge. So, they invented the writing system and the printing press.  We may run short of petrol in a few years.  We shall invent something to replace it.  So, necessity is called the mother of invention.
