A global warming phenomenon in our spaceship is one of several unintended effects of the unregulated, swift increase of 1) absolute global human population numbers, 2) per capita consumption of limited resources, and 3) large - scale business activities that could be occurring synergistically and approaching a point in history when it will not be possible for the Earth's resource base and frangible ecosystems services to sustain life as we now know it to be.
