How does the CDC address environmental health issues?

The correct answer highlights the proactive role of the CDC in addressing environmental health issues through monitoring and guidance. The CDC collects and analyzes data on environmental hazards, which allows for the identification of potential risks to public health. This monitoring is crucial for understanding the effects that environmental factors can have on health, such as exposure to pollutants or hazardous substances.

In addition to monitoring, the CDC provides evidence-based guidance and recommendations to mitigate these risks. This can include public health messages, strategies for communities to reduce exposure to hazardous substances, or tools for healthcare providers to help them understand the connections between environmental factors and health outcomes. By focusing on research and education, the CDC empowers individuals and communities to take action in promoting better environmental health and safety practices.

The other options, while they may play certain roles in broader environmental and public health initiatives, do not capture the specific and comprehensive approach the CDC takes in monitoring and addressing environmental health issues through risk assessment and public guidance.
