Earth has the happy confluence of gravity, water, and sunlight converging on one section of space, enabling it to raise flora and fauna for the rest of the solar system.

While there is still some limited fabricating and forging from raw materials, Earth cannot compete with low and zero gravity manufacturing establishments where raw material and power are virtually unlimited.

The people on Earth have the knack and skill to re-purpose off-world manufactured goods to all the gehaws, and gadgets a soul could ever need or want. Fashion and trinkets are always light-weight and have exaggerated pricing, thus ideal for export.

Of course Earth has the basics everyone needs: Fuel, grains, fabricated equipment, as well as the aforementioned trinkets and fashion. It is still home to mining, animal husbandry, aquaculture, farming, and tourism.

Grains pack tight and can be processed off-world for their burgeoning populations.

Fertilized fish eggs are bundled up to refreshen the genetic stock of asteroid farmed fish. In the long journey to their new home, they develop into young fry, ready to be placed in tanks hanging off the side of asteroids.

Salmon prefer a salty ocean and freshwater spawning to complete their life cycle, and a water bubble hanging off in space really doesn't cut it.

Fish are fine in outer space for a few generations, but with each tick-toc of the genetic clock, the stock seems to get weaker, or maybe they are just depressed, stuck in a wet blister on a rock spinning in the cold, weak sun stream.

Most of the critical manufacturing has moved to Luna with final assembly and polishing still active on Earth.

Electronics and parts are drop-shipped, literally, to assembly plants, pieced together and sold locally or for export back off-world.

Once off-loaded on Luna, H2LiftShips become drop ships for finished materials. Little energy is required in the transit from Luna to Earth using solar sails. Controlled descent through the atmosphere limits how much weight can be carried, but size is only limited by the volume that will fit in the cargo holds.

Earth has become much cleaner without having to continually rip up the surrounding countryside for metals and vast amounts of oil. Coal is still mined, but not burnt on Earth for the most part.

M type asteroids with abundant iron use Earth mined coal to make high-tensile steel and purify other metals, including gold.

Animal husbandry has made a comeback for Earths economy.

While it would seem to be simple to freeze and transport packaged goods instead of live animals, fresh food is considered a luxury that many can afford. There is also a small number of cultures/groups that need some type of living being for appeasement slaughter or to share with their community.

The profits made from shipping livestock far exceeds the effort to handle and maintain the animals.


With the re-greening of the planet, tourism to the garden spots of Earth is popular both for locals and off-world travelers.

Off-world, there are rocks, dust, and points of light against a black background.

For those whose "outside" strolls require breathing tubes and smelly space suits, the open, breathable air of Earth is earth-shattering, so to speak.

Parks on Earth are not the only a raison d' êtr ; it is cherished for its diversity. No other mass in the Solar system has breathable air, water oceans, Death Valley and the Sahara, rugged mountains with ice, snow, trees, and wildlife. It is, in a word, entertaining.

Speaking of entertainment, traveling to cities which are hundreds or thousands of years old, mixing with assorted cultures and eating their food is a perfect destination for those who get tired of hugging trees and sheep after visiting the parks.
