Answer:
that national parks are federal, not state land.
Step-by-step explanation:
The 1973 Endangered Species Act was designed to protect species of animals and plants which were at risk of extinction. Some people may not like wild species, but it is necessary to maintain the population to prevent the natural environment in the region from collapse. And therefore the federal government reintroduced wolves to the Idaho region by justifying federal rights over the state in this case.
