I believe our Earth goes through cycles. One of those uninhabitable cycles could destroy mankind. Another thought would be the 'fact' that our sun will burn out one day. We had better get our asses in gear to figure out where else to inhabit; otherwise, there will be billions of immortalists dying. I do, however, believe we are currently doing all we can to conquer this dilemma. Only time will tell though, and hopefully we will all have a lot of that on our hands.
Shouldn't this be the least of our worries? I mean, i'm completely sure that if the human race is still alive after a few billions of years, by the time the sun runs out of gas we will definitely have the means to do something about it. Probably most humans won't even be here on planet earth anymore.
There are more immediate problems for us to handle
That is where we are different on opinions. Why do you think that we are on a mission right now to find other inhabitable planets when none of them would be nearly as convenient nor beautiful as Earth?
