What will kill off mankind?

Another shout for greed. Throw in indifference to the mix as well. Sprinkle excessively with stupidity.

Read a sci-fi story once (might have been by Ray Bradbury) where creatures come to Earth to help out mankind. They can replicate anything from base elements - all they need is the original item.

Mankind becomes utterly reliant on them and, over many years, all manufacturing capability is lost.

The aliens gradually age, die, or just become dormant - plus, the copies they end up making are copies of copies of copies etc and they simply don't work.

Mankind becomes enraged and turns on their benefactors, attacking and killing them before beginning the descent into barbarism and extinction.

Lack of Bees or the Chinese rocket thats out of control atm. It’ll hit earth in a week or so. No one knows where yet but they’ll have six hours to predict once it re enters the earths atmosphere. Fill your car up.
 
A few humans will withstand most stuff that nature can throw at us and I think it would be fairly difficult to rid the planet of all of us.

If you could rewind the clock 500million people is a nice number.

I recall reading that story, no idea who wrote it or its title though, so not really helping :)

A pandemic. We can't get this one under control and as trite as it sounds the experts are correct - the world's not vaccinated until everyone is vaccinated and that looks fairly unlikely in the short-term, giving opportunity for mutation upon mutation.

Add in, if we keep decimating the planet there'll be an exponential growth in bat-eating transmissions to humans as we encroach further and further into completely unknown territories containing completely unknown viruses and disease.
