How would you foresee a modern apocalypse?

I'm guessing at some point there will be too many people to sustain. We'll have depleted the soil of all its nutrients, disrupted enough ecosystems, killed the oceans, caused drastic climate change and global famine will wipe out large portions of the population. I don't think the human race would die out entirely, but I don't think it can go on in the way it does now.
 
Sadly I am not expert on that field, but Interstellar mentions the issue of changes in the earths ecosystem. So much that humans could simply not survive anymore in the earths atmosphere. I am curious, what would it need to actually make such changes? Like, to really make it inhabitable for us, removing the oxygen or changing other factors that we need for our survival. And could humans actually change this, like over time?

If there's too much carbon dioxide and carbon monoxide in the atmosphere it would be toxic to breathe without a filter (carbon dioxide is merely asphyxiating, not directly toxic). The really problematic concentrations start around 7% or so for carbon dioxide, and current fresh air levels are less than 0.1%, so without volcanic activity it'd be hard to get there.
With large amounts of volcanic activity, maybe an anoxic event in the oceans and a few methane clathrates melting the atmosphere could sure be fucked. Standard extinction event stuff :D
