I dont see humans living on other planets for hundreds of years yet. Perhaps in 500 years first colonists will settle Mars, or some other planet.
But, with present tech and problems, nope. As for reaching a star; not for 10,000 years.
Why not resolve problems on Earth instead? Polution, water, food, wars, etc. have to be addressed. In India people dont touch nor eat cows, yet, millions are starving. North Korea is a failed state; as is Syria, Egypt, Lybia, Yemen, Afghanistan, etc.
Sending a few people into space wont address any problems. In time, the colonists will split into nations, and go to war against each other
anyway just as on Earth.
