> a huge part of humanity

That's the point there: We can easily wipe out huge parts of humanity. Huge parts yes, but the whole species? I don't think that's gonna happen unless something of a truly apocalyptic scale happens, and as ingenious we are, I doubt we are that ingenious to make that happen any time soon.

Note: I'm not saying everything will be just fine, I'm just saying we are a rather resilient species as we don't need actually that much just to "survive".
