I'd start the journey ... but it will take many many many generations to get there ... 1% of c is 2.7 million miles per hour ... or 470 years until we reach the closest star ... it's easy to get the fuel needed to get to that speed, but we'd have to carry with us the same amount of fuel to slow down once we get there ...
There's already life there, or the planet wouldn't be habitable ... so there will be pathogens that we have no defenses for ... whoever arrived would quickly die ... there's a 50% chance that proteins spin the wrong way there ... thousands of years of weightlessness, gravity alone would kill us ...
If we don't solve our problems here on Earth ... then we'd just take those problems with us ... so what's the point? ...
