| Résumé : |
The potential impacts on public health of global climate change pale by comparison to the ecological effects that are likely to occur. However, this is not to say that the public health consequences will be negligible, particulary in nations at an early stage of development. In the United States and most other developed nations, it seems that the greatest public health impacts will be on respiratory diseases. Health effects related to heat stress are also possible but the degree to which such effects occur will be dependent to a large extent on the ability of populations to adapt. This, in turn, will depend to some extent on the rate of climate change. If it occurs slowly, populations may have time to adapt. Poorer populations in the developed nations are also likely to be at greater risk than those with sufficient resources to afford mitigative measures, such as air conditioning. If perinatal mortality and/or preterm birth are exacerbated by summertime conditions, then its not unlikely that global warming will make these problems worse in the United States, which already has an abysmal record among the developed nations in premature birth and infant mortality.
In the developing nations, it seems likely that the potential public health consequences of global warming will be many. Impacts on agricultural productivity could prove devastating to countries that are only marginally able to provide adequate nutrition for their populations. If droughts occur, famine will follow and with famine and malnutrition. Malnutrition in turn results in lowered resistance to infection, so epidemics will be more likely. If vectors change venues, then we may also see significant shifts in disease and it is also conceivable that UVR will lower resistance, potentially also contributing to an increase in infectious diseases. These are not insurmountable problems, however, even without global climate change, starvation and disease are major problems throughout much of the world today.
Research is needed to determine what crops/cultivars are likely to be resistant to the impacts of the global climate change and to develop susbtitutes for any important crops for which no resistant cultivars can be found. It seems likely that any research to develop drought-resistant strains that are also heat tolerant will be very worthwhile . Much more research is needed into the immunologic effects of UVR and infectious diseases on humans. Furthermore, it is critical to determine if vaccination programs might be compromised by UVR and finally, the role of temperature/or humidity in reproductive effects such as perinatal mortality and preterm birth needs further exploration. |
