Would you find it more scary if you realized it applied to almost all mammals, not just humans? Species which are already facing severe pressure from habitat loss and fragmentation?
I share your view that human populations need a natural stabilization (and we've found it, by combining urban living with available birth control).
It's been too long since I looked into this issue, and I'm at work so don't have time to do the research now, but I remember studies showing that declining sperm count is a problem across multiple species.
