Why are we trying to colonize Mars, or the Moon, Whats wrong with being right where we are???

I don't believe that anyone has plans to colonize either one. Although exploration bases may be constructed, astronauts will be rotated in being there for any length of time. There are far too many problems involved such as radiation, gravity, and lack of sufficient oxygen among others which makes colonization improbable. These places are studied to learn more about the geology of our Solar System and we can use this to understand more about the history and makeup of our own planet. Man will most likely never permanently live anywhere except Earth.
