They’re framing this as a question but in reality it’s a statement advocating killing off the “unnecessary” population.

(James Cameron’s Avatar Wiki) — ‘There are too many of us already, and we must not let our numbers grow even further beyond what Earth’s resources can provide. If we want to keep/improve our current standard of living, those who are able should take precautions.

A few of the more extreme ideas (i.e. killing off “unnecessary” members of a population), while theoretically efficient, seem elitist and unnecessarily drastic and cruel from a human standpoint.

Then there are people who believe in the ideal that either nature or an all-powerful being will eventually “balance out” our growing numbers (Eywa?). Yes, people die every day, but lives taken by disease epidemics, natural disasters, or wars should not be thought of as expendable just because they were in the wrong place at the wrong time. In spite of the vast number of natural selection believers, we humans can take advantage of a very simple option to keep our numbers in check.

The total world population will reach about 9 billion in the year 2042, up from the documented 6 billion in 1999. Over 43 years, that’s a 50% increase, or an additional 3 billion people. That’s simply too many!

Some world governments presently have population limitation programs in place (China), or are developing new forms of contraception.
