your example is flawed. there are only 2 variables in your
example. the population, and the energy consumption per person. if
u change these 2 variables at the same time in the same example
without looking at other scenarios, the result u get is
meaningless.
if everyone chips in and saves 50%, its a lot saved.
if population increases 3 X, its a lot more energy used.
if everyone chips in and saves 50% while increasing population by 3
X, u use significantly less energy than u would
without saving.
therefore, saving is better than not.
people reproduce for the sake of doing it? 
wrong again.
in China, people want sons. that is a legitimate reason because
they want somebody to continue their blood name.
islamic countries... because Allah will get mad if they used
condoms/contraceptives.
back to Singapore, if people reproduced so much, the govt wouldnt
need so many FTs.
