I think the elephant in the room is population controls. No one likes the idea but at least passive measures by all governments need to be taken to curb total world population. We cannot sustain 10 billion people for long. We probably can’t even sustain 7 billion for much longer then the lifetime of some people alive today. Human expansion can continue, but it will have to be off-world. Earth population needs to be brought down into the low billions to achieve true sustainability with high quality of life.
