OverPopulation...

Our environment is the largest factor in the feasible population.  When we define world overpopulation as the maximum population that space ship earth can support, long term, we see that the problem will be the atmosphere, not food, water, or energy. We exceeded the carrying capacity about 1960. We are now at twice the capacity, we are screwed... oh well, in the end we all just die anyway. Now we need to go through population reduction, and that is a political burning hot coal that no one want to touch.

Forecasts suggest that population will level off at some about 10 or 11b. That is three times higher than the carrying capacity. That just will not work.

Some are pinning their hopes on new technology, carbon capture, or some other dream of what could be, maybe. Chemically, the best form to store the excess carbon in is solid form, or liquid hydrocarbon. That is all fine but fixing of carbon into solid form, so far, is only possible through photosynthesis, we have not yet even created an equivalent process in industry, the energy requirements are just too high.

So what does that all leave us with? Living in pods until we evolve?

Why is it so difficult to even get people to acknowledge this problem? 

What will the time look like? Refugees, leaving the worst overpopulated areas, migrating to less overpopulated areas. I doubt if there are any underpopulated areas now. Life will be brutal, hard, and likely short. There will be much civil unrest. Survival-ism will become even more popular. Government will break down. Police will be ineffective. Justice will become just a concept. Killing of immigrants may become a sport. Vial and brutal life can be expected. Oh well, we all just die in the end.

The life conditions will effect our ethics. Taking from those that have, aka the rich, will become routine. You cannot take from those who have nothing. Once we bet back down to a reasonable population, 50, 200 years from now, humans can try again to develop the good life.
