For the adventurous, a Moon Base is an appealing concept, but what would spur such a development? Due to the expense it is unlikely that personal gratification alone would warrant the creation of a "hotel" on the moon.
Exploitation of the Moon's resources is perhaps more likely to trigger a permanent Lunar settlement. Maybe you could conduct a literature survey to find out which raw materials scientists believe would benefit us? The Moon certainly attracts a lot of attention. Japan, India, China, Europe and the USA have all sent probes to the moon.
Of course, valuable natural resources are of strategic importance and it is not too far-fetched to imagine that disputes between interested parties could result in armed conflict and perhaps the first lunar war? This would be a far cry from the Moon landing of 1969 that stated "We came in peace for all mankind".
At the beginning of the 21st century NASA planned "The Constellation Programme", to send men back to the moon on a rocket called Ares - the Greek god of war and bloodlust! Sounds like this Lunar war's a "done-deal". Eventually, the Obama administration (wisely?) cancelled the Constellation Programme.
