Should we try to return the moon?

When a trip to the Moon will become more stable someday (after 100 years, 200 years), we should return to the Moon and I want to go there to see other planets and space.

Now, I think we should take more time or money to search the Mars in detail with following reasons.

Now, the Earth is having following problems and there is effective solution to solve those problems because each country has various situation in economical, culture etc and all of countries in the world can't take actions to solve those problems.

a) Air pollution
b) Water pollution
c) Ozone layer destruction
d) Global heating
e) Ecological change
f) Natural hazard

And I am very afraid that all things on the Earth like people, animal, forest, water can't stay on the Earth someday (after 200 years?).

I heard before that the Mars was silimar to the Earth and had water. In case of the Earth's crisis, we may need to move to Mars.

I think that it is be unlikely but not nothing, so I think that we should focus on the Mars investigation or try to find effective solution to save the Earth during the investigation of Mars.
