Step-by-step explanation:
Local Public Health Interventions
Among the examples provided, prohibiting smoking inside restaurants is an intervention implemented at a local public health level. This policy is a form of command-and-control regulation aimed at protecting the public from the harms of secondhand smoke, contributing to a healthier environment within public spaces. Other interventions include measures to provide clean and safe water, anti-bullying initiatives, and addressing nutritional needs of children.
Local governments may also enact policies to protect the environment which in turn benefits public health, such as keeping toxic waste out of local waters or selling permits for a controlled amount of pollution, which are forms of market incentive-based policies. These efforts align with broader public health goals, like preventing waterborne diseases and promoting clean air and better health through reduced emissions.
