Those are all great issues that definitely deserve attention. However, they're not problems that are caused by population. Everything you've listed are problems of the economic and cultural systems currently in place. None of these issues improves with a lower population.

For historical purposes, my previous comment revision was a thesis without links, and I replaced it instead with links to make the same point. My entire kingdom for HN comment version history support.

In short, very few will willingly forgo resources and give up quality of life, and for those who do will have those resources consumed by others (China harvesting the world's oceans, Brazil clear cutting the rainforest, etc).

My point isn't that people forgo resources but better utilize the efficiency and technology we've developed. We can maintain and better the quality of life for everyone. For example, at one point the US was wasting 51% of fresh food that has been distributed. Working on improving that distribution network can reduce food costs and waste. We have the technology.

Yet China wants more population. Are people criticizing that policity because lack of resources? If lack of resources is true, where is the outrage here? It seems more like some people are not willing to sacrifice lifestyle and instead sacrifice human population, not to mention there is huge asymmetry in the world when it comes to population.
