I don't get you and my statements weren't personal, so you don't need to take it personally and get offended. I wasn't having a go at your particular diet (how would I know what you eat - and yes it is very balanced, not everyone is) but the inconsistent attitude which you've only just seemed to make even more inconsistent by revealing you're vegetarian - vaccines and the side effects are acceptable, but meat and harming animals isn't, and additives/preservatives are okay but I don't really eat them. Talk about a head spin!

Anyway, I didn't say anything about a lower birth rate in third world countries, but a lower population. These are not the same thing. Logically, if that one child isn't dying from disease, the birth rate may drop by 1 per family, but the population would stay the same, or even grow because more females might reach the age of fertility because they're not dying. Considering most of these countries have high muslim populations, they're not going to be overly keen on certain contraceptions (if at all) so I believe education will make very little difference to their population. The only way I could see a massive drop in population would be from war, famine, natural disaster or fertility issues.
