Identify each author's primary criticism of the ESA and determine which statement

is not the problem. Rather it is lack of enforcement of other local, state, and federal laws

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? - Answers :Greater educational efforts to help citizens
understand the value of endangered species and ecosystems
If the ESA were revised by Congress, which combination of provisions would both
authors consider? - Answers :Strengthened enforcement of all federal ecosystem laws
and money earmarked for private landowner compensation
