Unhealthy environments can cause major diseases and lead to over 6 million deaths annually from stroke, ischemic heart disease, cancers, chronic respiratory diseases, and unintentional injuries. Young children and older adults are most at risk of environment-related deaths. Lower respiratory infections and diarrhea mainly impact children, while older adults face higher risks of noncommunicable diseases such as stroke, heart disease, cancer, and chronic lung diseases. Exposure to chemicals in cigarettes, asbestos, and indoor air pollutants from wood stoves or gas ranges can increase health risks like lung cancer and breathing problems.

3. How does an unhealthy environment affect us physically?
Young children and older adults have the greatest risk for environment-related deaths, WHO
officials said.
Lower-respiratory infections and diarrhea-related diseases mostly impact children.
Older people tend to have noncommunicable diseases such as stroke, heart disease, cancer,
and chronic respiratory disease.
Chemicals in cigarettes are known to cause lung cancer. Exposure to asbestos, an insulating
material found in some older buildings, can cause tumors, lung cancer, and other diseases.
Wood-burning stoves and poorly vented gas ranges can produce smoke or gases that can
cause breathing problems.

4. Across multiple environments, unhealthy environments are those that threaten safety, that
undermine the creation of social ties, and that are conflictual, abusive, or violent.
