Two interesting bits:
1km Tower Set For Construction In China
The “Phoenix Towers” are to begin construction in the city of Wuhan within a year and take 3 years to complete. They look very sci-fi/goofy.
Consider that China’s 1.4 billion people consume an average 2,970 Calories per day; this means that the Chinese population requires a whopping 2 quadrillion Calories each year.
With an average 8 million Calories per year for an average hectare of land (1 hectare = 2.47 acres), this means that China’s population needs over 250 million hectares, or nearly 1 million square miles, to sustain itself.
That’d be equivalent to a square farm 1,000 miles on a side. What do you think the chances are that China is going to go “green” with that… or are they going to burn as much carbon as needed to feed their people? In any event, China is necessarily going to import a whole lot of food. If you’re a farmer or fisher, this is good news. If you are relatively poor and have to buy food, this could be trouble.
