question 1=NO, it would be possible, with a global effort of resources being allocated to a project, but humans are dumb and we already have tons of problems here on earth that may never be solved, they could be solved but because humans are dumb and don't want eugenics, leading to war, overpopulation, damaging our planet with our dumb activities, and a lack of global cooperation.

question 2=yes i think going to space could extend our species survival, and i think it is possible with our current technology it would just require a lot of resources.

In the far term, a sail made of doped carbon nanotubes could probably approach the sun within 4 solar radii, and if it had an ac of 10 m/s2 , could reach α Centauri in a century. A sail made of doped carbon nanostructures could reach our nearest star in a few decades if ac >100 m/s2 as suggested by extensions of microwave theory.
here is something about solar sails,
It can thus be seen that the ultrathin solar sail holds the potential to revolutionize the prospects for interstellar travel. Uniquely, with this technology, such missions could not only become feasible, but potentially cheap, since all the motive power is provided in the form of crude sunlight – no giant lasers or other power systems are required.
