Untries of the Future
Welcome to The Stargazer Union, a new country of the
future on an off-world colony. In the year 2117, you 1) will
probably find lots of futuristic countries like this in space. By
just looking at conditions on Earth right now, it's easy to see
that homes on the moon 2) are going to get much more
popular. In fact, the Stargazer government 3) is going to
build even larger cities inside the giant glass bio dome to
welcome new visitors. That's not all! By 2117, the metal
and paper money of the past 4) will have ended, upgraded
to an entirely new digital currency. Here, in The Stargazer Union, society is very
advanced. In the years ahead, its industry 5) will be using renewable energy to
make a green economy that keeps everyone happy and healthy. More and more
governments 6) are developing new laws and eco-friendly schemes to help
towards this. So, take a good look around, traveller, and remember what you see,
because one hundred years from now countries 7) will not be the same again!
