Civilisation without Assimilation

What are we?
The mighty human race!
With medals, for history, we could trace
Or the genius of having predicted the future race

Funny isn't it? we left the present
Ignoring the lessons that were quite easy to be learnt
We mastered identifying the location, tone of skin, sound & script
But in our own race, we found ways how to be distinct

Ruining the natural balance of nature
By always keeping humans at the centre
We made many species go extinct
Forgetting that all creatures are interlinked

And all the focus on diversity never led to curiosity
To connect with each other, on the basis of enormous similarity
Did we so much fear the establishment of Parity?
that we brought the theory of pollution and purity.

Who defined these terms?
Our selfish means did
That valued own comfort
putting others lives in a bid.
