Why most of the people don't engage in humanity ???

Nowadays nobody engage in humanity activity .People become so selfish they only think about their well being and safety. As a human being we should follow humanity because it's a basic quality for human being. What happens to us , why we are loosing our humanity? Do you have any solution for this ?

Because nowadays people acknowledge one another as specific characters in their lives like Casual friends, work associates, and distant family members,So, they fail to realize the humanside of these characters which is why there is no humanity activites. We begin to use each other for our own purposes.
