Answer:
The law that permitted the reintroduction of gray wolves to Yellowstone national park was the Endangered Species Act 1973.
Explanation:
In the year 1970 a rigorous survey was carried out which found out that there was no specie of wolf in the Yellowstone.
The reason wolves were extincted in the first place was that they killed lower animals for food,which implies that if the situation is not corrected,other animal species are no longer safe.
