As shown in the last scene, on the "Eden" planet, there are about half a dozen ships departing after dropping off their presumed pair of children. So, including Caleb and Abby, there are maybe five other pairs of "Adam and Eves" to rekindle humankind. (Even if there are more ships across the planet, and thus more pairs of children, you will see that this is essentially irrelevant...)
According to Dana Krempels, PhD, of the University of Miami's Department of Biology, a single female rabbit can birth up to 14 bunnies. Dr. Krempels then goes on to base her estimates (http://www.bio.miami.edu/hare/scary.html) of rabbit reproduction on just three female offspring (rather than at least six to eight of that litter likely being female), using, again, a very conservative time frame of six months (a female produces a litter one month after impregnation and, in contrast to Krempels' six-month parameter, can become pregnant again almost immediately after giving birth).
By the end of the first year on planet "Eden," there would be approximately 37 female rabbits. By the end of Year Two, more than 1300 rabbits. Within three years, more than 50,000—and Caleb and Abby haven't yet even reached their teens...
So...keeping in mind that Caleb and Abby—and, likely, the rest of the young Adam and Eves—won't reach childbearing age for at least five years after arriving on "Eden" (probably longer), the rabbit population will be growing exponentially, with no competition from humans. By the time that each pair of "Adam and Eves" can produce one child—making, at most, a half-dozen offspring across this "Eden" planet—rabbits will outnumber humans by the tens of millions, and, as you can see from Dr. Krempels' Year 6 and Year 7 estimates, the population will further explode into the tens of billions, with no end in sight. The ecosystem will be overrun, and eventually destroyed, by rabbits, forcing humanity into extinction. Even if the kids learn how to construct rabbit traps and acquire a taste for hassenpfeffer, they won't put a dent in this leporine ascendancy. Besides, enjoying such dominance, rabbits will probably grow to gargantuan proportions, as in Night of the Lepus, and begin to feed on the humans. Regardless, all traces of human existence would be gone from this rabbit-packed planet in a handful of years.
At an adding machine, the quick-witted, and quick-breeding, Bugs retorts, "From me, doc! I'm multiplyin', see? I'm multiplyin'!"
Like the 50-year-old page of apparently random numbers that serves as humanity's warning of its doom in Knowing, "The Big Snooze," itself, serves as a warning for those to be spared in Knowing. Of course, Caleb and Abby might be too young to ever have seen "The Big Snooze"—and certainly too young to have grasped its message even if they had—but John Koestler (Nicolas Cage's character), like anyone of his generation, almost certainly had seen "The Big Snooze" at some point in his life and, being a professor of astrophysics at MIT, unquestionably should have understood its dire warning of a race that humanity simply cannot win.
Thanks for nothing, benevolent aliens!
