Have you got any numbers on that?
I am aware that things are becoming more efficient, but we are still adding a lot of people to the world. And more and more people are moving from relative poverty to more western lifestyles and corresponding increased levels of consumption.
There is some debate surrounding this, known as Jevon's paradox. There have also been some papers where the rebound effect has been studied and found to be low to moderate, so efficiency improvements do have a positive impact:
Indeed the population is still increasing, but population growth is decelerating. Population will likely plateau within the next 70-80 years, and then possibly decline.
