The relationship between climate change and health is one that concerns many people, because of the serious negative impacts environmental factors can have on “at risk” populations: children, the elderly, and the impoverished. For more information about current environment-health issues, such as the dangers of pesticides used on crops (which children are especially vulnerable to due to their small size), check out the Health section of the David Suzuki Foundation.
So why are certain populations more vulnerable than others to the negative effects of climate change? For starters, children and the elderly have less strong immune systems than most adults, making them more susceptible to diseases and extreme weather events like heat waves. According to UNICEF, the United Nations Children’s Fund, children are most vulnerable to climate change, and those in East Asia and the Pacific are most at risk. According to Geoffrey Keele of UNICEF, “The leading killers of children worldwide are highly sensitive to changes in the climate…For example, higher temperatures have been linked to increased rates of malnutrition, cholera, diarrheal disease and vector-borne diseases like dengue and malaria. Yet children’s underdeveloped immune systems put them at far greater risk of contracting these diseases and succumbing to their complications.”
The U.S. Environmental Protection Agency’s “Climate Change and the Health of Children” website explains more about the issues that children face specifically: They provide links to background information on technical environmental and health issues for those who want to learn more.
For potential strategies for preventing these climate-related health problems for children, check out “Global Climate Change and Children’s Health: Threats and Strategies for Prevention” provided by the U.S.’s National Institute of Environmental Health Sciences’ Environmental Health Perspectives Journal. It explains issues such as children’s susceptibility to excessive heat and provides examples of different climate-sensitive events children are exposed to throughout their lives, and possible effects.
