Earth Resources VS Population | WORK IN PROCESS

The World population is slated to reach 10 Billion by 2100 according to the United Nations, but is that really a problem?  Lets look at some numbers:

Planetary Dimensions:

  • Naam-Limits-of-Earth-Part1-001-earth (600x600)

    Diameter:  7,901 miles (12,715 km)

  • Circumference:   24,901 miles (40,075 km)
  • Surface Area:  197 Million sq miles (510 Million sq km)
    • OR  126.34 Billion acres (51 Billion hectares)
  • Land Area:  57,47 Million sq mi  (148.85 Million sq km)
    • OR 36.78 Billion acres (14.88 Billion Hectares)
  • Ocean Area:  139.93 Million sq miles (361.15 sq km)
    • OR 89.56 Billion acres (36.24 Billion Hectares)
  • Mass:  6,613.86 Quadrillion tons  (6 Million Quadrillion kg)
    • Crust (2.18%):  144.18 Quadrillion tons (130,800 Million Quadrillion kg)

Planetary Space Calculations:

  • Breathable Atmosphere:
    • Extends upward 30 miles (50km).
    • Total Volume:  4.4 Billion Cubic Miles
    • Total Volume Over Land:  1.46 Billion Cubic Miles
    • Total Volume Over Water: 2.93 Billion Cubic Miles
  • Continental Crust:
    • Extends Downward 13 miles
    • Total Volume:  628.7 Million Cubic Miles
  • Oceanic Crust:
    • Extends Downward 4 Miles
    • Total Volume:  390.667 Million Cubic Miles

Planetary Land Resources:

  • Total:  57,47 Million sq mi  (148.85 Million sq km)
    • Or… 36.78 Billion acres
    • Or… 3.67 acres per person
  • Farming (11%):  6.32 Million sq mi (16.37 Million sq km)
    • Or… 4.04 Billion acres
    • Or… .4 (four tenths) acres per person
  • Pasture (25%): 14.36 Million sq mi (37.21 Million sq km)
    • Or… 9.19 Billion acres
    • Or… .9(9 tenths) acres per person
  • Cannot Produce Food (63%):  36.21 Million sq mi (93.78 Million sq km)
    • Or… 23.17 Billion Acres
    • Or… 2.3 acres per person

    NOTE:  Using vertical farms, we can make current land 20-30 TIMES more productive. We can also build them on unusable land, or in the ocean.

Planetary Water Resources:

  • Total:  296 Million Cubic Miles (326 billion billion gallons)
  • Saltwater (98%):  290 Million Cubic Miles (319.48 billion billion gallons)
    • Or… 31.95 Billion gallons per person
    • Or… 137 Million TIMES current annual global water consumption
  • Glacial Ice (1.6%):  4.74 Million Cubic Miles (5.216 billion billion gallons)
    • Or… 520 Million gallons (10.4 Million Barrels) per person
    • Or… 2.2 Million Times current annual global water consumption
  • Fresh Water (.8%):  2.37 Million Cubic Miles (2.608 billion billion gallons)
    • Or… 260 Million gallons (5.2 Million Barrels) per person
    • Or… 1.1 Million Times current annual global water consumption

    NOTE:  With recent developments in electrolysis, filtration, and evaporation cycling, we can desalinate ocean water much cheaper than ever before.  In addition, by switching to aeroponics we can reduce the amount of water consumed by farming, which consumes 92% of fresh water, by 90%.  Meaning we can reduce our consumption to 17% of what it is today.

Population Density Possibilities:

  • Mumbai, India: 53,600 ppl/sq mi (83.75 ppl/acre) = 186,567 sq miles
    • Or… roughly the size of California
    • Or… .3% (3/10 of 1%) of the earth’s land area
  • New York:  27,000 ppl/sq mile (42 ppl/acre) = 370,370 sq miles
    • Or…roughly the size of Texas and New Mexico Combined
    • Or… .6%(6/10 of 1%) of the earth’s land area
  • Boston:  12,000 ppl/sq mile (19 ppl/acre) = 833,333 sq miles
    • Or… roughly a little smaller than Texas and Alaska combined
    • Or… 1.5% of the earth’s land area
  • Salt Lake City:   2,232 ppl/sq mile (4 ppl/acre) = 4,480,290 sq miles
    • Or… an area larger than Canada, but Smaller than Russia
    • Or…7.8% of the earth’s land area

    NOTE:  We can achieve much higher population densities…upwards of  a million people per square mile…by building much taller sky-scrapers and deeper “ground-scrapers”.  With existing technology we can build up to a mile (5,280 feet) in either direction.  In addition we can create artificial islands and live on the oceans.

Food Consumption For 10 Billion

  • 1/2 lb of meat per day (190 lb/year) per person
    • 5 billion lbs (2.5 million tons) per day
    • 1.8 trillion lbs (913 million tons) per year
  • 2.2 lb of dairy per day (800 lb/year) per person
    • 22 billion lbs (11 million tons) per day
    • 8 trillion lbs (4 billion tons) per year
  • 1.9 lb of plants (700 lb/year) per person
    • 19 billion lbs (9.5 million tons) per day
    • 6.9 trillion lbs (3.5 million tons) per year
  • 0.6 lb of grains (232 lb/year) per person

Food Production Options

  • Traditional Horticulture:  1,125 lbs (0.55 tons) beef/acre per year
    • 0.17 acres to produce 190 lbs per person each year
    • 1.7 billion acres (2.6 million sq miles) to feed 10 billion people
    • 4.6% of total land area
    • 12% of total pasture land area

    NOTE:  To be conservative, I have assumed that everyone will get all the meat in their diet from Beef because it is the most expensive food, requiring up to 8 lbs of grain to produce 1 lb of meat…in addition to the feed lot.  If we grow the grain in vertical farms, the amount of land needed for horticulture decreases dramatically.

  • En Vitro Meat:  100 tons/Story Acre per year
    • 9.13 million acres (14,265  sq mi) using single story buildings
      • .0009 acre per person
      • 0.02% of total land area
      • 0.08% of pasture land area
    • 1.5 million acres (2,344 sq mi)using 6 story buildings
    • 304,333 acres (476 sq mi) using 30 story buildings

    NOTE: Cellular production is continuous, allowing for much higher yields.  This could be in the order of tens of thousands of tons per acre per year, but I have limited it to 100 tons to be conservative.  In addition, it removes the need for slaughter-houses and can be grown directly in the factory.   This greatly reduces the need for transportation and cuts its industrial footprint by more than half.

Aeroponic Agriculture 16,000 lbs (8 tons) Per Story-Acre

Total sq miles /acres needed for 6 story buildings (Percentage)
Total sq miles /acres needed for 30 story buildings (Percentage)
Total sq miles /acres needed for 150 story buildings (Percentage)
Total sq miles / acres needed for 300 story building (Percentage)

NOTE:  On small plots, aeroponics has been shown to increase crop yields by up to 10 times  that of traditional farming while reducing the use of water, fertilizer, and pesticides by 90-95%.  However, commercial vertical farms have been shown to only produce 1.6 times the normal yield per story-acre…I have used this amount to be conservative.
