interesting numbers

[philw]

was talking with one of the blokes at work  re populations 

we looked up   how big is Australia to USA   and the size of cities

also   with how big  we are compared to Europe   


yet  90%  or so  of our population  is around the City's 


interesting to look at though

Similar to China.  I used to think China was a very large country but it turns out it has about the same area as the USA.

Like Australia, 90% of it's population is in the cities along the coast.

I would guess that most countries have 80% to 90% of their populations living in cities/suburban areas.  I found some other interesting tid-bits concerning how the world's land mass is utilized.

Land Use Statistics - About 30 percent of the surface is exposed land and 70% is covered by water.  This land usage is broken out as follows:

Arable land: 13.13 percent (of the 30%)

Defined as: Land cultivated for crops like wheat, maize, and rice that are replanted after each harvest

Permanent crops: 4.71 percent (of the 30%)

Defined as: Land cultivated for crops like citrus, coffee, and rubber that are not replanted after each harvest; includes land under flowering shrubs, fruit trees, nut trees, and vines, but excludes land under trees grown for wood or timber.

Permanent pastures: 26 percent (of the 30%)

Forests and woodland: 32 percent (of the 30%)

Urban areas: 1.5 percent (of the 30%)

It is estimated that 12.5% of the Earth’s surface is suitable for humans to dwell.  The 1.5% above is a fraction of the fraction.  If my math is correct Urban Area's occupy just .05% of the total Earth's surface.   In reality, people occupy an insignificant percentage of the Earth's surface.

Other: 30 percent (of the 30%)

Interesting that there is more land suitable for crops (13.13 + 4.71 = 17.30) than is suitable for human dwelling (12.5).  I guess no one would want to live in a rice paddy...but I wonder what other crops are like that?
