Kurt, I appreciate your presentation of the statistics above.
Mark Twain, my favorite satirist, once said: "There are three kinds of lies; lies, damned lies and statistics." Taking that into consideration, I present the following:
From the United Nations Department of economic and social affairs
21 June 2017"The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today. With roughly 83 million people being added to the world's population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline....."
The report continues here:
My take away from the report is; at least through 2100, the overall world human population will continue to increase. In fact, if one believes the projections, the planet will have to accommodate an additional 3.2 billion human beings by the beginning of the next century. That is roughly 82 years, or the span of a single human lifetime.
Bringing the conversation back on track, at what point, exactly, do you foresee the actual population of the world beginning to decrease, not just a reduction the rate of growth? Keeping in mind that trends of the past several decades cannot reasonably be expected to represent trends over the next couple of centuries.
In the meantime, it would appear that without alternative energy sources, human beings will continue to dump massive amounts of CO2 into the environment, increasing the temperature of the oceans, which in turn will result in a cascade of changes to the global climate.
My original question still stands, with the human population continuing to expand, how do we accommodate everyone without drastically and negatively changing our planet? From my perspective, it would seem that eliminating the burning of organic fuels and replacing them as a source of energy with technological sources, would go a very long way to accommodate our population growth, at least with regard to stabilizing the climate, food production and water treatment.
Or, we could use Gfe's approach and scrub a few billion people off the planet with thermonuclear weapons......
