Ans✅ ✅: A) Several ESA "success" stories are species that were already on the
increase before their ESA listing.
Question: Identify each author's primary criticism of the ESA and
determine which statement below accurately describes one author's
comments.
A) Knight: The problem is labeling species as endangered that are
already in recovery.
B) Davison: The problem is the shift away from ecosystem protection to
individual species.
C) Knight: Allowing private landowners to destroy habitat is the primary
problem with the ESA.
D) Davison: The ESA itself is not the problem. Rather it is lack of
enforcement of other local, state, and federal laws aimed at ecological
integrity.
Ans✅ ✅: D) Davison: The ESA itself is not the problem. Rather it is lack of
enforcement of other local, state, and federal laws aimed at ecological integrity.
Question: Knight suggests that many private landowners deliberately
destroy endangered species habitat because they are not reimbursed by
the federal government. Compare this with Davison's observations about
the public. What action do you think Davidson would recommend based
on his essay?
A) Widespread private landowner protests against the federal
government
B) Federal compensation for private landowners
C) Greater educational efforts to help citizens understand the value of
endangered species and ecosystems
D) A thorough revision of the ESA
Ans✅ ✅: C) Greater educational efforts to help citizens understand the value of
endangered species and ecosystems

Question: If the ESA were revised by Congress, which combination of
provisions would both authors consider?

earmarked for private landowner compensation
B) Offering land swaps for endangered species habitat while eliminating
other federal laws that duplicate the intent of the ESA
C) Limiting the ESA to only include species found on public land
D) Tighter restrictions on which species can be listed as endangered or
threatened
Ans✅ ✅: A) Strengthened enforcement of all federal ecosystem laws and money
earmarked for private landowner compensation

biodiversity of the species.
