Which of the following is an example of a direct health impact of environmental hazards?

  1. Reduced property values

  2. Respiratory illnesses

  3. Economic downturns

  4. Increased community awareness

The correct answer is: Respiratory illnesses

The choice of respiratory illnesses as the correct answer reflects a direct health impact of environmental hazards. Environmental hazards, such as air pollution, exposure to toxic substances, or poor water quality, can lead directly to health problems in individuals. For instance, inhaling polluted air can cause a range of respiratory issues, including asthma, chronic bronchitis, and other lung diseases. These health effects are attributable directly to environmental conditions rather than secondary economic or social consequences. Reduced property values and economic downturns relate more to the socio-economic effects of environmental damage and are not health outcomes themselves. Increased community awareness is essential for addressing environmental hazards but doesn't represent a health impact in terms of physical health outcomes. In contrast, respiratory illnesses clearly illustrate how environmental hazards can manifest directly as health problems for individuals and communities.
