For the condor to survive in the wild, its breeding population must be greatly increased  But because only a few eggs can be produced by a breeding pair over their lifetime, any significant increase in the number of birds depends upon most of these eggs hatching, which is extremely unlikely in the wild due to environmental dangers
One possible way to eliminate the effects of these factors is to breed the birds in captivity and subsequently return them to the wild
If more condor eggs do not hatch, the condor as a species will not survive in the wild.
