Which of the following illustrates an environmental strategy in community health?

The correct option illustrates an environmental strategy in community health because advocating for policy changes directly impacts the environment in which individuals live. Environmental strategies focus on modifying the external conditions that influence health behaviors and outcomes. By pushing for policies that may restrict access to harmful substances, enhance regulations on alcohol and drug use, or promote healthier community infrastructures, advocates can create a safer and healthier environment for all community members.

In contrast, while creating peer support groups, hosting educational workshops, and promoting substance-free events are all beneficial initiatives, they tend to be more focused on individual-level interventions or community engagement rather than systemic change. These activities are essential for building community capacity and support, but they don't inherently alter the broader environment in which health decisions are made. Environmental strategies aim to create widespread change that ultimately makes healthier choices easier and more accessible for everyone, which is achieved through effective policy advocacy.
