First of all What is soccietey:
"A society is a group of peolpe involved in persistent social comiunactions , or a large social group sharing the same spatial or social area, typically subject to the same political authority and dominant cultural expectations. " Acording to Wikipedia
So know you know what socsitey is so Why do we need society?
1. Societies create modles of behavior by allowing some activtes or communication as okay or not okay. They show us with a floor to take and develop social positions.they also are an important guide for a grreat life ..
Therfore, Societys are mportant because they give us with a system and a polices to work unitedly for the better.
"it was created by our ancestors and is been revising since its inception by us according to our different needs, comfort and behavior.Why this happens because, we evolve, from our survival instinct to socio-productive skills. It is the later skill which separates us from animals up to an extent because in nature there is only one truth- survive or die. The line between society and nature is very subtle. Without nature there is no society, hence they are byproduct of nature. ..The prominent belief behind creating it is to make a shift from our animalistic behavior to something better because we are endowed with imagination, we can think of something better and create it."
"Without society the human beingwould cease to exist. Society is important because it is NATURAL to us humans and in fact MANY other animals as well. From birth, we areplaced into group settings and situations with particular common denominators: family, schools, government and political systems, etc"
Hope this helps
