One of the reasons that u. s. environmental policy is so difficult to pass is because
a. most of the arguments for environmental policy do not have the support of scientific evidence
b. human behavior tends to focus on short-term needs over long-term processes
c. international agencies cannot agree on policy
d. environmental policy is not typically equitable for all citizens

Option B, human behavior tends to focus on short-term needs over long-term processes, is the right answer.

Explanation:

The action of the federal government of the United States to control and regulate the activities that make an impact on the environment is known as the Environmental policy of the United States. The main objective of such a policy is to protect the resources and environment for the forthcoming generation. The government tries to interfere as little as possible in commerce or the freedom of the people and limiting the injustice in who is afflicted with environmental damages. However, the behavior of humans to concentrate on short-term requirements over long-term means has remained one of the reasons that the environmental policies are difficult to pass.
