Anthony, your point is valid, but's its an interesting cultural double-edged sword, isn't it? I mean the US, Japan and Western Europe are all seeing a decline in birth rates, yet it is the muslims who are immigrating to Europe to fill the gap, and Catholic south americans in the US. So you're one grandchild will be speaking spanish or arabic, or probably chinese. So everyone has to stop procreating at the same time, kinda like nukes...
