what is the reason behind discrimination of different particles (human & inhuman) in this world?

A) Off-course the whole world has been made of five elements (human and inhuman). The common thing  among the particles is pancha bhutas (5 elements) but we see lot of discrimination, such discrimination is because of the diffrence in the presence of All-mighty that is sannidhana vishesha.
शुद्ध्यशुद्धी विधीयेते समानेष्वपि वस्तुषु ।
द्वव्यस्य विचिकित्सार्थं गुणदोषौ शुभाशुभौ ।। (भागवत)
पञ्चभूतात्मकत्वेन समता सर्ववस्तुषु ।
हरिसन्निधान वैशेष्याद् विशेषश्च महान् सदा ।। (भागवत तात्पर्य निर्णय)
