Explain carbon dating kids

We also know that the ratio decreased during the industrial revolution due to the dramatic increase of CO produced by factories.

And yet we know that "radiocarbon is forming 28-37% faster than it is decaying," which means it hasn't yet reached equilibrium, which means the ratio is higher today than it was in the unobservable past.The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.So, if we find the remains of a dead creature whose C-12 to C-14 ratio is half of what it's supposed to be (that is, one C-14 atom for every two trillion C-12 atoms instead of one in every trillion) we can assume the creature has been dead for about 5,730 years (since half of the radiocarbon is missing, it takes about 5,730 years for half of it to decay back into nitrogen).
