Resources. (also works for water) http://en.wikipedia.org/wiki/Asteroid_mining
In 1997 it was speculated that a relatively small metallic asteroid with a diameter of 1.6 km (0.99 mi) contains more than $20 trillion USD worth of industrial and precious metals.[6][27] A comparatively small M-type asteroid with a mean diameter of 1 kilometre (0.62 mi) could contain more than two billion metric tons of iron–nickel ore,[28] or two to three times the annual production of 2004.[29] The asteroid 16 Psyche is believed to contain 1.7×1019 kg of nickel–iron, which could supply the world production requirement for several million years. A small portion of the extracted material would also be precious metals.
Farming. http://www.verticalfarm.com/more
Advantages of Vertical Farming
Year-round crop production; 1 indoor acre is equivalent to 4-6 outdoor acres or more, depending upon the crop (e.g., strawberries: 1 indoor acre = 30 outdoor acres)
No weather-related crop failures due to droughts, floods, pests
All VF food is grown organically: no herbicides, pesticides, or fertilizers
VF virtually eliminates agricultural runoff by recycling black water
VF returns farmland to nature, restoring ecosystem functions and services
VF greatly reduces the incidence of many infectious diseases that are acquired at the agricultural interface
VF converts black and gray water into potable water by collecting the water of
evapotranspiration
VF adds energy back to the grid via methane generation from composting non-edible
parts of plants and animals
VF dramatically reduces fossil fuel use (no tractors, plows, shipping.)
VF converts abandoned urban properties into food production centers
VF creates sustainable environments for urban centers
VF creates new employment opportunities
We cannot go to the moon, Mars, or beyond without first learning to farm indoors on
earth
VF may prove to be useful for integrating into refugee camps
VF offers the promise of measurable economic improvement for tropical and subtropical
LDCs. If this should prove to be the case, then VF may be a catalyst in helping to reduce or even reverse the population growth of LDCs as they adopt urban agriculture as a strategy for sustainable food production.
VF could reduce the incidence of armed conflict over natural resources, such as water
and land for agriculture
