The resources required to traverse interstellar distances are astronomically greater than terrestrial travel (pun intended). Most species die out. How long do you believe it will take to have human explorers on the nearest extrasolar planet. And that's the easiest, closest one. Then think about how many species go extinct on this planet. There's no certainty that we will survive long enough to explore that far.
