You can act like these are all tiny details, but tiny details are what lead to big things going wrong further down the line.

Or what if species that normally migrate get killed off, and the species they usually eat reproduce too much and overwhelm *their* ecosystems?

That's another thing, too. Environmental collapse (the deaths of multiple species) in one geographic location can affect species in other geographic locations, including non-human species.

It wouldn't take that long for a major fish kill to affect island populations.

Like yes, I'm sure there's extremely rural communities of people who would survive a nuclear war, and maybe live decades before environmental radiation and/or the deaths of external species and critical biomes eventually took them out?

You're being overly literal about this.

If irradiating the atmosphere isn't a big deal after all, then why aren't we just disposing of nuclear waste by shooting it into space and risking a garbage shuttle explosion?

Everywhere on Earth is connected to everywhere else, and everyone lives on the same planet/depends on this planet's resources; it's surprising how often people seem to forget this?

"Radioactive ashes won't literally rain down from the sky and block the sun, and the bombs will only hit major population centers" yeah man but idk if you've heard of this thing called The Water Cycle? Or, like... The wind?

its only social contagion if its gay, duh
