Yes, the UN does need to consider the safety of people. If there is a possibility that the Chinese Space Station is going to fall in an area where people are present instead of falling into the ocean, people need to be warned, and the tragedy needs to be prevented if possible.
This could be a serious problem for safety of people on Earth. UN must talk with Chinese representatives within the UN and consider the level of risk for the people on Earth and what are the chances that the parts of space station will hit populated area, and what precautionary measures will Chinese Government take to protect the people in that case. Also, UN must consider what impact would that event have on the environment, or to be more precise, are there any radioactive materials on Space station which could damage the environment.
Yes, the UN should intervene with China's falling space station because it is important for countries to be able to develop the ability to explore. By helping the space station grow, children will be more interested in space and many more people will enter the workforce to help in the future.
By the time it lands there wont be much left and will certainly not cause much if any damage (if it did manage to hit anything). G g g g g g gg g g g g g g g g g g g g g g gg gg g
No, the United States should not intervene in China's falling station, because it's not likely to land somewhere where it will cause significant damage. There are other space stations that the U.S. can use to conduct research. It's just not an issue the public needs to spend American resources on at this time.
