Certain regions on Earth have had an outsized impact on trade in important commodities. For instance, the Middle East has been important because of the amount of oil some in the countries there. Without those huge oil reserves, much less global attention would have been paid to conflicts in that region.
The international treaty that governs the exploration and exploitation of space by the members of the United Nations forbids the placing of weapons in Earth orbit or on other astronomical bodies. One of the great fears is that a space faring nation could place nuclear weapons in orbit which would give it an advantage in a possible exchange of nuclear warheads with another country.
Currently, the main habitat space in Earth orbit is the International Space Station. Its future is in doubt with the U.S. only allocating funds until 2024. Many of the nations and private companies involved in space exploration and exploitation support the continued presence of human beings in orbital habitats.
I have been blogging a lot lately establishing a manned base on the Moon.
The International Space Station is a habitable man-made satellite in a low orbit above the Earth. It is the largest man-made body in orbit and can be seen with the naked eye. It is made of pressurized modules, external trusses, solar arrays and other components. The first components were launched in 1998 aboard Russian Proton and Soyuz rockets and United States Space Shuttles.
