What do you think will destroy the human race ?

I have a few possible theories:

First, The Human race will ultimately be the doom upon mankind itself. You know what, that is probably happening too and we do not even know it.

Second, If Apophis makes its impact on the Earth in 2036 or 2043, it will not be pretty either way. (Hits water, hello Tsunami. Hits land, hello Volcanic Ash-like Dust blocking out the sun and causing a cooling period for decades for that region.)

Third, in Futurology, the Sun has 5 Billion Years left, but the Earth will not exist by then. Since by the time the Sun will start using up all of its hydrogen fuel and it becomes helium and it expands. The shift in gravity will cause magnetic storms in the Earth's atmosphere as well as changes in temperature because the magnetosphere is disrupted by this sudden change. Every 64,000 years the Magnetic poles shift as well, though NASA.gov says this will not have a major effect when it does happen.

Four: The Earth's oil is like its blood. We're using it nonstop. There's going to be a time when there will be no oil left. Because people are fracking in order to get to the oil, drilling deeper. There's a limit to how far you can drill for oil.

Five: There's a futurology theory on how the Earth's core can break down. Currently gravity is having an affect on the Earth by causing it to cave on itself. If you notice that the Earth is not a perfect sphere like some atlases will say. There's a gravity dip in the poles and gravity is also a tiny bit stronger towards the poles as well. The Earth's core is another way to know that the Earth does have a life of its own. The core is like its heart, it can break down as it ages and uses up the energy like how stars use up their own fuel, expand and die.

Six: God will invoke his wrath and destroy the Earth as he's depressed and fed up with everything. When a God attempts a suicide, you know you effed up.
