Root causes of Global Warming, i.e., global climate change

Nearly nobody seems to notice or want to talk about the connection between burgeoning human population, degradation of the environment, exhaustion of natural resources, and reduction in quality of life.  There is a connection -- and a causal relationship.  Meanwhile, good Christians, Catholics, Mormons, Muslims, Hindus, et al, continue to reproduce themselves willy-nilly because their religions and relatives tell them to, so they'll have someone to take care of them when they're old, and to maintain an illusion of immortality.

Of course, most people want and have kids, and only a cad doesn't love children.  That's why the discussion ends before it begins.  "...for whatsoever a man soweth, that shall he also reap." (Galatians 6:7 KJV, Christian Bible)

However, there is a glimmer of hope to be seen.  In time, the population of industrialized countries becomes stable.  (Why?  You tell us.)  The only exception is, as usual, the U.S.A., but in that case it's due to its immigration policy (or lack thereof).  Unfortunately, industrialized countries are enormously wasteful and polluting, and they have an insatiable thirst for oil.  So let's look for a country whose energy needs are satisfied by a non-carbon energy source.  When and where will it happen?  Will its population stabilize?
