Millions of Pages of Previously Classified Documents on Industrial Poisons (and Counting)

Mardi, à l'occasion de la journée mondiale de la santé, la France et l'Indonésie organisent à Lyon le sommet One Health («Une seule santé»). Face aux crises écologiques qui se multiplient, cette nouvelle approche veut concilier la santé des humains, des animaux et de l'environnement. Explications.

Maladies d'origine animale, pollutions, résistance aux antibiotiques : ces sujets communs aux santés humaine, animale, végétale et environnementale alimentent les échanges lors d'un sommet international organisé par la France depuis lundi à Lyon. Emmanuel Macron s'y rend mardi.

Dans une tribune au « Monde », plus de 700 scientifiques, personnalités politiques et membres de la société civile insistent, en amont du One Health Summit, qui se tiendra à Lyon le 7 avril, sur l’urgence à mettre en place une règlementation européenne ambitieuse sur la question des pesticides.

La majorité des maladies infectieuses retrouvées chez l’humain vient des animaux ; on parle de zoonoses. C’est par exemple le cas de l’influenza aviaire, ou grippe aviaire, responsable de nombreuses infections chez les oiseaux et de rares cas chez l’humain. Pour la filière avicole comme pour d’autres, repenser les modes de production grâce à l’agroécologie pourrait aider à prévenir les risques sanitaires. Une réflexion qui résonne avec l’approche « Une seule santé » (One health, en anglais) qui lie santé animale, humaine et environnementale

Dans une étude publiée ce mercredi 1er avril par «Nature Health», des chercheurs ont identifié dans le pays d’Amérique latine des zones exposées à des pesticides non classés cancérogènes pour les comparer aux registres locaux de la pathologie.

There is mounting experimental evidence that lifetime exposure to increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. Directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. This has the potential to cause a range of adverse health effects.

Harmful chemicals in babies’ pacifiers. ‘Forever chemicals’ / PFAS in dental floss. Known carcinogens in lipstick lids. These are just three examples of toxic chemicals in everyday products that reveal how the EU’s flagship chemicals policy, REACH, is not delivering for citizens.

Climate change could lead to half a million more deaths from malaria in Africa over the next 25 years, according to new research.

Breathing in air pollution like ozone and PM2.5 harms nearly every major system in the human body

The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.

“Water crisis” has become the default label for almost any episode of water stress, from short-lived droughts to decades-long overuse of rivers and aquifers. Yet in many regions of the world, water problems no longer resemble a crisis in the conventional sense. They represent a post-crisis failure state in which human–water systems have exceeded their hydrological carrying capacities, and societies have spent beyond their sustainable hydrological budgets for so long that critical water assets are depleted, some ecosystem damages are irreversible on human time scales, and a return to “normal” is infeasible even with prohibitive economic, social, and environmental costs.

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petroleum-based waste and heavy metals have been discovered in pesticide and plasticizer formulations. These contaminations have now reached all forms of life. Widespread exposure to chemical mixtures promotes health and environmental risks. We discovered that pesticides have never undergone long-term testing on mammals in their full commercial formulations by regulatory authorities or the pesticide industry; instead, only their declared active ingredients have been assessed, contrary to environmental law recommendations. The ingredients of these formulations are not fully disclosed, yet the formulations are in general at least 1000 times more toxic at low environmentally relevant doses than the active ingredients alone u

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

Five of the seven breached planetary boundaries are linked to food systems. By transforming production and adopting a “planetary health diet,” we can halve food-related climate emissions and prevent millions of deaths, according to the 2025 EAT-Lancet Commission.
