We are currently at the brink of extinction, ironically by overpopulation. Everyone knew rapid growth is unsustainable, with 7.9 billion people on earth right now, we are causing more: Carbon emissions, global warming, pollution, environmental damage, ozone depletion etc.

Soon we won't have a planet to live in. I am sure mother nature will find more subtle but beautiful way to eradicate us.

But, hopefully we leave this small planet and explore other planets in near future.
