Love is what makes the world go around. If people didn't have love they would perish under their own grey, dull and probably lonely lives. Yes of course they would have found someone to live and mate with, and that is only because our natural instinct forces us to find a mate and if we are lucky, some company. Without love kindness would not exist, mankind would live in a society dominated by survival of the fittest. Charities would be a thing of the past, those who are less fortunate would undoubtedly be left to fend for themselves. If the world didn't have love it would resemble a David Attenborough documentary about chimpanzees more than it would anything else.
Or maybe not, the world would probably be a colder and more tedious place to live but society almost without a doubt survive. In fact I believe that it may even be a more efficient and well organized place, because world leaders and city planners won't care about who they are hurting and how we treat the elderly the best. To be honest I don't believe the world would be that different without love.
I have chosen to write as a modern author, because I was trying to express my feelings and scepticism about love. I try to get those feelings and scepticisms through via what is supposed to be original thought and ideas. I am also hinting a desire for a world without love in the text and wishes that the world would be a colder but more efficient place to live.
If i had chosen another author functions like e.g. playwright I would probably write about in the form of a story where my opinions got through via characters
