Nevertheless, things are improving - even if not fast enough. The Millennium Development Goal of halving the proportion of hungry people by 2015 may well be achieved (see FAO website, report for 2013). The fad for biofuels doesn't help, by using land that could be used for growing food.

The earth's resources are finite, but then we only need them for a finite length of time, to provide finite needs for a finite number of people. How all these finite quantities balance out is not necessarily easy to predict in advance. I wouldn't bet against our being able to sustain 20 billion people (100 years ago it would have been brave to predict that we could sustain 7 million) but I very much doubt we will have to try.
Global warming is a reality (as global cooling has been in the past) but not necessarily a catastrophic one (at least until the sun becomes a red giant in around 5 billion years). 'Someday' (probably) is a long way off. Probably we shall populate planets and moons before then.
