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.
