Indeed, it is not only about climate change anymore it is rather about a much wider large-scale and long-term Environmental crisis with unpredictable and irreversible impacts on biodiversity in general and the global health of humans in particular.
The combined effects and consequences of the ongoing degradation in biosphere, hydrosphere and atmosphere on biodiversity and human health would create severe health threats for all life forms on planet Earth. These degradation are brought about by environmental (e.g. pollution and waste) and climate change because of green-house gases specially carbon-dioxide. There are already signs of such effects but not yet understood and systematically researched. Such wicked and complex problems are new in science in general and medical ones in particular, They can’t, and will not, be cured by medical treatments and far beyond human capabilities to deal with even if the multilayered unknowns will be known. The functioning and metabolism in our bodies depends very strongly on the environmental conditions including the temperature. This wasn’t known for Darwin.
The UN General Assembly in September 2021 will bring countries together to meet again at the biodiversity summit in Kunming, China, and the climate conference (COP26) in Glasgow, UK. This time is about the serious situation what concerns the risks to health of increases above 1.5°C, which are now well established. The call in this post is stating that “Indeed, in the past 20 years, heat related mortality among people aged over 65 has increased by more than 50%. Among other things higher temperatures will bring about increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality. Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities, and those with underlying health problems”.
Editorial Board of BMJ for emergency action to limit global temperature increase, restore biodiversity, and protect health (https://www.bmj.com/content/374/bmj.n1734). As stated in this article “Health professionals are united with environmental scientists, businesses, and many others in rejecting that this outcome is inevitable. More can and must be done now—in Glasgow and Kunming—and in the immediate years that follow. We join health professionals worldwide who have already supported calls for rapid action.”
Though the current attention ⚠️ is focused on climate change we have to take in consideration many other large-scale and long-term threats that are associated with the increasing environmental degradation from pollution and waste. This calls wider actions to promote and implements the UN-SDGs.
