There two critical issues facing the world and they are access to potable water and to oil.

You should change the word "oil" to "energy".

And there is a third critical issue and that is unchecked/out of
control population growth.

There is only a finite amount of oil and supplies will eventually
dwindle no matter how much is newly discovered. At some point it will
become expensive enough that burning it for energy will be
unthinkable. It will have much more value as an industrial/chemical
feedstock.

On the other hand, if global population growth is not reigned in, no
amount of water or energy will be enough.

Let's see, one of my first papers in college was about population growth, with the Club of Rome
being a source of information. This was in the early 70's. That would be about 40 years ago, and I
don't see the population growth dwindling by much.
