Good luck dreaming about colonizing other planets.

If you believe the doom sayers and alarmists, you will have a very negative opinion. "Overpopulation" has been a repeated theme for THOUSANDS OF YEARS. Each time, the elite trot it out to excuse their "thinning of the herd of useless eaters."
And you may have misunderstood the part about colonizing outer space. I do not refer to "colonizing other planets." I refer to fabricating ginormous self sufficient autonomous space habitats to orbit our sun, planets, moons, and so forth.
[] Space colonization via habitats - a better idea

http://settlement.arc.nasa.gov/Basics/wwwwh.html#why“. . . The key advantage of space settlements is the ability to build new land, rather than take it from someone else. This allows a huge expansion of humanity without war or destruction of Earth's biosphere. The asteroids alone provide enough material to make new orbital land hundreds of times greater than the surface of the Earth, divided into millions of colonies. This land can easily support trillions of people.”
. . .
TRILLIONS OF PEOPLE.
1000 BILLION.
. . .
And that's a conservative estimate.
MCKENDREE CYLINDER
http://en.wikipedia.org/wiki/McKendree_cylinder
McKendree’s design would use carbon nanotubes instead of steel, allowing the habitat to be built much larger.
Habitat would consist of two cylinders approximately 460 km (290 mi) in radius and 4600 km (2900 mi) in length, containing 13 million square kilometers (5.1 million square miles) of living space - nearly as much area as the nation of Russia.
.....
^^^ The computed surface area only refers to one layer - the outermost shell. If the cylinders had nested layers, the surface area is far, far greater.
76560 decks (10 ft)
2 x 10,127,094,564.45 sq.mi.
= 20,254,189,128.9 sq.mi.
Capacity :1,012,709,456,445 (@50 per sq.mi.)
1.01 trillion people
PER COLONY.

DYSON SWARM - pack ‘em in like sardines
EARTH Aphelion : 152,100,100 km / 94,500,000 miles
Orbital Circumference : 955,673,113.5 km / 593,761,011.5 miles
@4000 km spacing : 238,918 colonies could fit on the plane of Earth’s orbit.
MARS Aphelion : 249.2 Gm / 166.96 million miles
Orbital Circumference : 1565.77 Gm /1,049.07 million miles
@4000 km spacing : 391,442 colonies could fit on the plane of Mars’ orbit.
And those figures do not count "cyclers" (that orbit between planets), or inclined orbits.
And imagine adding banks of colonies extending to the orbit of Venus and out to the Asteroid belt. (Not too sure about approaching Jupiter’s orbit - but who knows?)
. . .
Let’s spitball about 40 billion McKendree sized colonies with 358 trillion space colonists each, roughly holding 14.32 e+24 (septillion) humans. (We’d hit that around 4200 A.D. at current population doubling.)

Futurists are divided into two categories or groups: doomers and boomers.
❏ Doomers (Malthusians / Machiavellians) assume that there is no hope for humanity, and shall destroy the earth from wasting irreplaceable resources.
❏ Boomers (Cornucopians) believe that applied science and technology offer a hope for humanity, especially by colonizing outer space, where there are 'astronomical' amounts of resources, power and expansion room.
I am a cornucopian, and don't plan on accepting genocidal "environmental preservation."
