you are too fucking retarded to grasp OP's basic point so let me spell it out for you.
humans are natural. anything humans do, any secondary effects from our actions are ultimately just nature running its course.
besides, species evolve, shift their ranges and destroy each other in nature all the time. it's not some sort of divine perfect balance, it's a never ending brutal rat race where every creature is just barely holding on, most of the time. evolution ruthlessly optimizes things to just barely manage to reproduce before getting killed by something else.
