It is now well understood that the current and future climate and environmental crises significantly affect the health of populations. These crises raise several major issues, each as worrying as the next. These are mainly the changes in temperature and the heat waves that they generate, air pollution with the resulting spread of vector-borne diseases, and changes in ecosystems that promote the progression of infectious and parasitic diseases. These extreme weather conditions are affecting food production, leading to shortages, price increases, and nutritional deficiencies that are of great concern. These deficiencies also concern water resources with waves of drought linked to changes in rainfall patterns that can lead to water shortages, which dramatically affect hygiene and consequently the risks of waterborne diseases such as diarrhea including cholera and other infections. These environmental disasters also lead to massive migrations of populations, endangering their physical and mental health due to their precarious living conditions in refugee camps which increase the risk of infectious and nutritional diseases and those related to significant stresses that can lead to mental disorders such as anxiety, depression and post-traumatic stress disorder.
