I have a bit more of a controversial opinion on this, but it basically stems from the fact that there's too many people on this planet. Living is too easy, the strongest and best of our species aren't the only ones surviving and thriving. It stems from mental illness and it's breeding like an infectious disease and it pollutes our gene pool.

Thanos has it right, if 50% of the human race disappeared in a mere second, Humanity would be better off for it.
