How does this relate to public health?
Carbon dioxide is also a major contributor to global warming and climate change via rising temperatures. Warmer temperatures may lead to increased frequency and severity of heat-related illnesses and reduced water and air quality, which in turn have a variety of adverse effects on human health. These include increased risk for cancer, foodborne and waterborne illnesses, cardiovascular and respiratory diseases, vector-borne (caused by bite from insects) and zoonotic (diseases that can be spread from animals to humans) diseases, mental health and stress-related illnesses, and human developmental effects.1
