<p>In Tenga Toppa Gurren Lagann, there was a part where after they defeated the beastmen, Rossiu forced everyone to come up to the surface, even those who didn't want to. Never really fully understood why he did this. After all, if I recall correctly, Lord Genome already warned them what happens when the surface population of humans reaches 1 million. A census on those who live underground doesn't make sense to me. So why did he do this?</p>

Why did Rossiu forced the ones who lived underground to come up to the surface?
