Yes, that's what I meant when I said I'm all for space exploration. But, most of the reasons to leave the planet Earth from us general public have been in the line of "I'm fed up with all this and that's why I have to go to the Mars to start anew" i.e. mostly running away from the problems or fed up of the system etc.

That being said, in my opinion, we should definitely pay more attention to saving this planet rather than finding new ones and doing the same thing all over again.

I sincerely think we do pay more attention to this planet than Mars, e.g. many people advocating mars are also involved in electric cars and solar energy.
