2 points.
1. I don't see wealth or "distribution" of wealth as an issue with people having more children and an increasing world population. We should take someone's wealth and give it to someone else because of over-population? I don't follow you here.
2. Yes, people - and in particular parts of the waster resources and have things they don't need.
#2 has some relation to my point that a. humans use resources (yes some more than others and some are wasteful). b. There are too many people in the world, IMO.
As for using resources, let's look at people in China and India, the West and anywhere driving cars and motorbikes that pollute the air.
