There is a proverb in India, that says killing the teacher by the skill learnt from him, it may not be literal all the time, often it is symbol of destruction.
Human beings have mastered this skill quite ironically.
They learned flying from birds, and now their flying threatens birds, by the sound and emissions.
They learned sonar skills from whales and now they are muddling up their behavioral patterns.
How much damage one single species can cause an entire planet… human beings might rank top if we go on a galactic search in future.
I wonder in other planets, that have life, are there any other examples of a species as intriguing as human being, with so much knowledge but due to brazen abuse that knowledge is harming everyone around them.
