L’humain adapté, plutôt que l’humain augmenté.

L’humain adapté plutôt que l’humain augmenté : en 2023 l’adaptation aux enjeux environnementaux constitue un objectif essentiel en particulier pour le secteur de la santé humaine. Les interactions entre la santé humaine et les enjeux environnementaux sont multiples. Il peut s’agir par exemple de réfléchir aux nouvelles conditions climatiques et aux conséquences des perturbations à venir. L’association Human Adaptation Institutehttp://, mène des recherches en ce sens à travers le monde  : «  the Human Adaptation Institute aims to better understand the cognitive and physiological mechanisms of human adaptation in facing rapid or long-term change. Our studies are carried out in real life situations, solely on humans, in an equal manner and considering all physiological, cognitive and ecosystem parameters impacting the notion of Adaptation. Our results enable us to better prepare for the future as well as to propose levers of action beforehand in order to reduce possible impacts. The Human Adaptation Institute aims to better understand the cognitive and physiological mechanisms of human adaptation in facing rapid or long-term change.”

Parmi les perturbations possibles, apparaissent déjà avec évidence les perturbations du système reproductif humain. Certaines technologies, par la pollution qu’elles induisent et les influences de substances chimiques, ont des conséquences négatives sur les mécanismes de reproduction, la baisse spectaculaire de la fertilité des humains en témoigne : “To name just a few, air pollution and increased ambient temperatures have been suggested to increase the risk of preterm birth, low birth weight and stillbirth. Higher ambient temperatures have also been associated with increased prevalence of vector-borne diseases, and with reproduction in mind, zika and malaria would be of concern for their known severe complications with fetal development. The abundant use of plastics is also thought to negatively impact our reproductive health due to their endocrine-disrupting chemical properties. Reports published in Environmental Research and Public Health and Environment International have detected microplastics in human tissues: testis, placenta and umbilical cord, as well as associating microplastic exposure to ovarian fibrosis and oocyte and semen quality. Following these findings, it would be ethically irresponsible to continue as normal without any progression towards sustainability in the way we work. Arguably, without change, we would no longer be fully upholding the Hippocratic oath to ‘do no harm’ » explique Fran Farlie, embryologiste, Concept Fertility à Londres, dans la revue en ligne BioNews (1).

Si chacun se doute que le secteur de la santé humaine est impacté par le changement climatique, l’inverse pourrait paraitre moins évident. Or cet impact du secteur de la santé sur les conditions environnementales est loin d’être négligeable. L’humain de demain va peut-être devoir adapter, non seulement sa propre santé, mais aussi les structures dédiées à préserver cette santé : “As one of the largest economic sectors globally, health care represents nearly 10% of GDP spending across O.E.C.D. countries. This significant activity produces an estimated 5-10% of global greenhouse gases, presenting opportunities to directly reduce this impact through changes to energy supply, waste, purchasing, and care models. Equally important, health care has a special interest in addressing climate change. Across the globe, human health is negatively impacted by the ramifications of climate change, such as heat, storms, flood, and fires. The health care sector must provide leadership on this critical issue to protect and improve the health of its patients. What should the role of the health care sector be when it comes to climate change policies and advocacy?“. Une conférence Climate Change and Health est organisée le 10 février prochain ( Register for this Event), par Harvard Medical School et Petrie-Flom Center for Health Law Policy, Biotechnology, and Bioethics at Harvard Law School.
