I don't think population growth itself is a bad thing, in fact from an economic standpoint you want a positive population growth, but not too high. I believe the sweet spot is around 1% is argued to have a positive effect on the economy. Decreasing population is a bad thing (ie Japan) and too much is equally if not more detrimental as GDP per capita won't be able to keep up. A quick search of countries with highest birth rates kind of shows the disparity in economic conditions there https://www.statista.com/statistics/262884/countries-with-the-highest-fertility-rates/

While the numbers you posted above seem huge, they're also under 1% growth per year which I think is pretty reasonable on a global scale. If we go back to 1900 the world population was 1.6B. If it grew at the same rate as these statistics, the population would only be 4.87B by 2011, not 7.3. This is about a 1.37% yearly growth while we're predicted at only a much more modest .66% growth to hit 8B by 2024.

Whats More important than the growth itself I think, is how the population will be distributed. We'll likely see more mega cities and recent estimates show that Asia may contain 75% of the world's middle class by 2030. Just a personal opinion, but I think the balance in world power may shift even more in favor of AP then as well as many of the countries appear to be very open to attracting great talent and invest largely in human capital. It will be interesting for sure
