Some Populations of Sea Turtles and Galapagos Tortoises Are Maintained

Some populations of sea turtles and Galapagos tortoises are maintained by people who collect their eggs and hatch/rear the young in captivity. Why is this practice supported by conservationists?

A) The eggs are given only to people who need high protein.
B) It is an inexpensive way to raise young turtles and tortoises for food.
C) Introduced species can be effective predators and consume all or most of the eggs that are laid.
D) This is a good way to census the wild populations.
E) You want to prevent both species from over-reproducing.
