As metropolitan cities continue to grow at incredible rates alongside each other across the globe, their boundaries start to blur. This has given rise to a new scale of geography known as "mega-regions". These vastly populated settlements have interlocking economic systems, common natural resources and shared transportation links....According to a new UN report, the world's mega-cities are merging to form these vast mega-regions which may stretch hundreds of kilometres across countries and be home to more than 100 million people. _AsianInfrastructure_via_BrianWang
The Hong Kong-Shenhzen-Guangzhou region is home to over 120 million people and it is here where a significant chunk of China's economic boom is happening.
..."The top 25 cities in the world account for more than half of the world's wealth. And the five largest cities in India and China now account for 50 percent of those countries' wealth," he added....Asian cities are growing more equally according to the report, but primarily because they were already uniformly poor with a greater volume of slums. _AsianInfrastructure
As the populations of the world huddle together in ballooning megalopolises, what will happen should something suddenly go wrong? What if war breaks out, and the enemy targets civilian infrastructure such as power, transportation, communications, water, fuel, food delivery, sanitation, health care facilities? What will 100 million people packed together to the gills, do when faced with sudden loss of food, water, fuel, medicines, and such?
Clearly, the strong will prey on the weak, until there is no one left to prey on but other predators.
If a diabolical green leftist scientist wanted to eliminate at least 90% of the human population, the task is made so much easier by the concentration of hundreds of millions of people into small areas. Under such conditions, the effect of the EMP, or the bioengineered lethal virus or toxin, will be magnified. Particularly with the calculated demolition of particular bridges and highway overpasses.
A highly centralised population is a highly vulnerable population -- vulnerable to a decapitation strike. The simultaneous loss of transportation hubs, research and production centers, centers for delivery of health care, and destruction of food, fuel, and water distribution along with bureaucratic infrastructure -- would likely lead to rapid collapse and terminal disorder. Particularly when the same thing was happening to most of the megalopolises of an entire region or continent.
The technology of the 21st century will allow for comfortable rural living -- a reversal of the compulsive urbanisation the 20th century bequeathed to the early 21st. But we have to learn to use it, then make the choices that allow us to break the chains that tie us to the urban lifestyle. Otherwise we are the ones who tie ourselves to the railroad tracks while the black-suited villain in the background pulls the track switch lever, sending the hurtling train our way.
Take your pick of black suited villains, but as long as the radically insane third world nations such as North Korea, Iran, and Venezuela are not allowed to possess reliable nuclear weapons and delivery systems, it is most likely that the threat will come from within high tech societies themselves.
The radical greens have never made a secret of their wish to cleanse the planet of most of humankind. Let's not make it any easier for them than we have to.
