Peak oil, peak food, peak water, global warming too. Is the root cause of all of these problems that there are just too many people on the planet?
The current world population is about 6.6 billion and growing fast. Yet suggesting that we need less people opens up all manner of ugly issues. Who gets to decide how to limit population growth? What will the rules be? Will it be voluntary? And in what countries?
Less Developed Countries are understandably highly suspicious of such proposals coming from the prosperous countries. There is also the undeniable problem of masked racism, with some using this as a pretext to get rid of Those People.
Malthusians say that limited resources on earth at some point will not be sufficient to feed the planet so that leaves us with what, that a good healthy die-off is what we need? This does present a teensy ethical dilemma, hoping for hundreds of millions to die so the rest may live better.
But the question remains: Are there too many people on the planet competing for too few resources?
