The World Health Organization (WHO) has worked for individual, national, and global health for 45 years. Soaring populations, mounting waste products, and ill-advised use of natural resources has led to environmental degradation. This adversely affects humanity’s health and the health of Earth itself.

 

Vienna stamps address regional/national, and continental/global environments. The national level deals with disaster preparedness and energy policy. The global level monitors atmospheric and oceanic pollution, and international standards and policies.
