This article that I stumbled upon some weeks ago is now over 10 years old. It doesn't contain any brand new information, but it is pretty insightful and informative in it's own way.
Do read the entire thing. It's rather pertinent to us living in India, at least, with all the "let's blame all our country's woes on the population".
Those who fear overpopulation share a simple insight: People use resources. They eat food, drive cars, and take up space. Because resources are scarce, the only way to improve living standards, Malthusians argue, is to limit the number of people with whom we have to share these resources.
The rebuttal to this argument is equally simple: People create resources. They bring into the world their time, effort, and ingenuity. Before deciding whether world population growth is a curse or a blessing, we have to ask ourselves whether an extra person added to the planet uses more or less resources than he or she creates.
