Direct to the moon (won young sin)

I think living in the moon is not possible because human can not live without air and water and there is no gravity in the moon. In farther future, we can live there maybe but it is not easy to transfer all the people in the earth because moon is smaller than Earth.
However, I think living in the moon will be quite fun because going to space and moon was one of my dreams.
You know why scientists are planing to live in the moon? This is because the Earth is too polluted by human. If the Earth pollutes continuously,human cannot live in Earth even 200 years.
In the space, Earth is only one planet which has suitable conditions for living things. I think conserving our earth is more better idea than living in the moon.
