Regulation refers to the rules and guidelines established by governments or organizations to control and manage specific activities or industries. These rules are designed to protect public interests, ensure safety, and promote fair competition. For example, financial regulations help maintain stability in the economy by overseeing banks and investment firms. Regulations can cover various areas, including environmental protection, health and safety, and consumer rights. They are enforced by regulatory bodies, such as the Environmental Protection Agency (EPA) in the United States, which ensures that companies comply with laws aimed at preserving natural resources and public health.
