“We are actually quickly approaching the point where the birth rate will drop so tremendously that under-population will be revealed as the true threat. …
“The number of births taking place worldwide have been in sharp decline over the past 20 years. If this trend continues then the world’s population will quickly peak and then begin a mysterious and dangerous decline.
“Every single time throughout history that the human population has increased significantly as we have seen in the past few centuries, the commoners have been told that the growth of their community would result in chaos and mass scarcity of resources.
“Of course, these predictions have never come to pass because the Earth’s human population actually has very little to do with the scarcity that exists on this planet.
“The scarcity of resources that leads to many of our major problems is the result of the actions that humans are taking while on this Earth — if people respected each other and their environment then we could easily sustain another 7 billion people on top of what we already have.”
“Over the past 30 years the worldwide population growth rate fell from more than 2.0 percent to 1.5 percent a year, and experts expect this trend to continue. … Today’s low-income countries still have the world’s highest birth rates, although women tend to have fewer children than before.” Source: The World Bank “World Population Growth“
My Comment: The great Kabbalist of the early 20th century Baal HaSulam wrote that our planet can feed dozens of billions of people if only they would think about providing food to all the people on earth.
