"More people, please: don't worry about the booming global population -- celebrate it"!
Very enjoyable article from the magazine "Foreign Policy" about the benefits and opportunities of a larger global population:
"...In Bangladesh, despite low incomes and poor health, 85 percent of the population suggests they are happy, and in Nigeria and China that number is nearly three quarters. Simply put, having the opportunity to be alive is a good thing, and the more such opportunity exists, the better. (Another bit of good news from the U.N. projections -- average global life expectancy will rise from around 68 years today to 81 in 2100, so we'll all have a little bit longer to enjoy it.)"
I don't think pro-lifers could endorse all of what the writer says about family planning in the third world, but the central point is very important.
