Final answer:
Federalism and separation of powers in environmental policy often result in overlapping jurisdiction, leading to complexities in creating uniform environmental regulations due to variations in state needs and resources.
Step-by-step explanation:
According to the text, federalism and the separation of powers regarding environmental policy often result in overlapping jurisdiction.
While the benefits of federalism include political participation and policy innovation, its disadvantages include the potential for cross-state disparities and impeding federal efforts to address national problems. In the environmental policy context, these overlapping jurisdictions can arise because different states may have different environmental needs based on their natural resources and industries.
This may lead to conflicts when a single federal agency, like the Environmental Protection Agency, endeavors to impose a one-size-fits-all regulatory framework.
