User blog comment:Mohrpheus/Spiritual Imbalance in Bleach - The End of the World?!/@comment-44061-20100830232425

Well lets take this into account. Say for arguments sake there are millions of Hollow not counting the Menos-class and then there are more millions of those that are of the Menos-class. Thats alot of Hollows but if we take real world numbers into account there is a total of about 6 billion people on the planet. Now its way more then that figure if you add every living soul from the beginning of human civilization. Now seeing as time goes by and throughout human history we have people despairing in droves every generation from day 1 to the current time. There must be alot of hollows in hueco mundo reaching back centuries if not more. Now truth be told your right if 1 menos is made of 1000 of hollows thats alot of hollows who maybe have also claimed alot of innocent souls in their existence that dont get saved.

I think the point was regardless of the numbers Shinigami purify hollows and thus they are returned back to the cycle. Quincy destroy them thus they are removing them from ever becoming part of the cycle again. Shinigami are part of that cycle they govern souls, they perform soul burial and they purify hollows. Quincy have no such mandate. I dont think the numbers where that big of an issue. The issue was the cycle. Regardless a Hollow was gonna be purified and balance would be maintained. Yes the numbers can be staggering but there is a balance the good and the bad the negative and the positive. There has to be the existence of hollows if they devour souls then they always can be purified and continue the cycle. Them eating a large amount of souls would stand to reason is a necessary thing as well because there can only be so many souls in the cycle or overpopulation in the world of the living would also become a problem.

The actual issue was "Shinigami govern the souls between the Human World and Soul Society, which maintains a balance that if not kept would result in the mutual destruction of both worlds. All souls, including Hollows, are subject to the Shinigami governance of maintaining the balance. Quincy completely extinguish Hollows. Thus the souls that come to the Human World do not return to Soul Society and therefore the souls would increase only on the side of the Human World. Meaning, the Human World becomes heavy in souls causing Soul Society to spill over into it; mixing life and death. The ultimate result would be the end of the world."

Basically the souls have to come to soul society before entering the human world again, the flow of souls must be controlled. Something the Quincy can't make happen. Thats why they got wiped out. Hollows are the necessary evil that have to be taken care of if they cause trouble in the Human World or Soul Society but otherwise are left to their own devices in hueco mundo. But I agree Shinigami response time isn't that great.
