"Does it bother you at all that we are overpopulating the Earth?"
Yes & no.
I believe this sort of thing is self regulating, but how it will regulate itself is very concerning. Ultimately we have three options to use, but in what combination remains to be seen:
1. Lower birth rate.
2. Higher death rate.
3. More resources.
According to World Bank statistics, population growth has been slowing since the 60's, but it's still exponential growth. They have it pegged at 1.2% which is alarming considering our current population. A quick calc using the rule of 72 would imply that, at the current rate, our entire population could double in the next sixty years or so.
Granted there are variations in the growth rate of populations across geographies, but this is still a recipe for poverty, bouts of shortages, and the violence which accompanies inequality.
...I just had a thought will typing this. I wonder if rising fuel prices will actually delay some of the effects of overpopulation. If shipping costs rise substantially we may go through a period where it is no longer cost effective for many 1st world nations import a lot of their food. This may then force some of the more impoverished countries to reduce exports of cash crops and restructure their economies. That may either make local markets more attractive, or lower the cost of agricultural land enough to put it back into the hands of domestic farmers.
It's a lot of "may"s and "if"s, but one can always hope we avoid yet another famine where food is being exported and aid has to be imported.
