I just want to comment on WBT's line:
> ...someone has to pay for not having enough children.

I am internally shocked when I hear people say that. I was talking with a person some months ago who firmly believed that part of our economic problems were caused by the slowing of population growth. Shocked the first time.

Then I read an article a few weeks about trouble in China due to their population decline. Shocked the second time. (Search Google news for "china population decline" to see the articles.) I am appalled that people think that population growth should continue. There is a finite amount of resources in this world, and for every new human, there is that much less to go around, and in the current world, there is that much more demand for cheap fuels.

WBT's line reminds me a third time.

I cannot believe people will not consider the future impacts of their present actions.
