World Population Growth History and Challenges
1. World population reached 1 billion people in 1800.
2. It took another 127 years to double to 2 billion people in 1927.
3. It took only 48 years to double again to 4 billion people in 1975.
4. It took just 48 years to double again to 8 billion people in 2023.
Therefore, in less than 100 years the world human population has quadrupled!! What will happen if the human population doubled again? Seemingly that would happen sometime this century and some people alive today will likely be alive when that occurs. How would we feed 16 billion people? And would someday about 100 years from now would there be a need to feed 32 billion people?
The potential solutions would be challenging and likely would include:
1. Converting wildlife lands to farms, thus driving many species to extinction or near extinction.
2. Converting suburban home lawns to farmland.
3. Inventing/building high tech skyscraper farm buildings that don't use soil to grow crops.
4. Very restrictive laws on how many children families can have (likely just 1 which is something that China does already) or if some families can have children at all.
Will some nations that are having trouble feeding their population invade neighboring nations who still have land resources for additional farmland? Based on human history, most likely yes.
Will their be energy shortages and also shortages of key resources such as steel, wood, salt, materials for clothing, etc.? Most likely yes.
Will a future atomic war occur that would result in a much smaller human population?
