Question

____ is often protected through regulations to prevent future emissions. ______ is often ensured using a series of filtration process, and ________ can be preserved through remediation?

Answer 1

Command-and-control and market incentive-based are types of environmental policies used to regulate pollution. Bioremediation is a method used for environmental cleanup.

Step-by-step explanation:

The student's question centers around environmental protection mechanisms. Air quality is often protected through regulations to prevent future emissions. Water quality is often ensured using a series of filtration processes, and contaminated land can be preserved through remediation. Let's classify the given pollution-control policies:

A state emissions tax on the quantity of carbon emitted by each firm is a market incentive-based policy.

The requirement by the federal government for domestic auto companies to improve car emissions by 2020 is a command-and-control policy.

The setting of national standards for water quality by the EPA is also a command-and-control policy.

A city selling permits that allow firms to emit a specified quantity of pollution is another market incentive-based policy.

The federal government paying fishermen to preserve salmon is a market incentive-based policy.

Moving on to specific waste types, dioxin-bearing wastes, chlorinated aliphatic hydrocarbons production, and wood preserving wastes, among others, can have significant environmental impacts and often require remediation to manage.
