La pollution est la destruction ou dégradation d’un écosystème ou de la biosphère par l’introduction, généralement humaine, d’entités (physiques, chimiques ou biologiques), ou de radiations altérant le fonctionnement de cet écosystème1. La pollution a des effets importants sur la santé et la biosphère, comme en témoigne l’exposition aux polluants et le réchauffement climatique qui transforme le climat de la Terre et son écosystème, en entraînant l’apparition de maladies inconnues jusqu’alors dans certaines zones géographiques, des migrations de certaines espèces, voire leur extinction si elles ne peuvent s’adapter à leur nouvel environnement biophysique.

.. the real risk of geoengineering is not some Hollywood-style catastrophe, but complacency. A cheap way to delay the effects of warming risks undermining the need to rapidly reduce emissions, and going down that path would risk locking our children into a dependency where even stopping the process becomes too expensive to contemplate...
We make meaningful climate action faster and easier by mobilizing the global tech community to track greenhouse gas (GHG) emissions with unprecedented detail.
EU officials warn climate breakdown and wildlife loss ‘are ruining ecosystems that underpin the economy’ […] The European way of life is being jeopardised by environmental degradation, a report has found, with EU officials warning against weakening green rules. The continent has made “important progress” in cutting planet-heating pollution, according to the European Environment Agency, but the death of wildlife and breakdown of the climate are ruining ecosystems that underpin the economy.
Almost 100 countries reject draft treaty as ‘unambitious’ and ‘inadequate’
Forever chemicals have polluted the water supply of 60,000 people, threatening human health, wildlife and the wider ecosystem. But activists say this is just the tip of the Pfas iceberg
When a small Swedish town discovered their drinking water contained extremely high levels of Pfas, they had no idea what it would mean for their health and their children’s future
The world's largest polluters are also the safest from the environmental damage they help create—while the countries least to blame face the greatest threats, including the increased possibility of violent conflict.
Russia’s war in Ukraine has encouraged a rapid increase in the deployment of drones that use fibre optic cables to protect them from being jammed or downed by electronic warfare: the drones trail kilometres of plastic cable across frontlines. In this post Leon Moreland explores the environmental risks posed by this new form of battlefield plastic pollution.
Small particulate matter (PM2.5) in air pollution raises the risks of respiratory problems, cardiovascular disease, and even cognitive decline. Heat waves, which are occurring more often with climate change, can cause heatstroke and exacerbate conditions such as asthma and diabetes. When heat and pollution coincide, they can create a deadly combination.
Toxic pollution from wildfires has infiltrated the homes of more than a billion people a year over the last two decades, according to new research. The climate crisis is driving up the risk of wildfires by increasing heatwaves and droughts, making the issue of wildfire smoke a “pressing global issue”, scientists said.
A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers.
A microplastics and toxic chemicals expert says her family doesn't wear shoes at home. Microplastics from car tires and garbage, as well as street runoff, can be tracked indoors on shoes. The researcher thinks her kids' Japanese heritage helped them adopt the habit.
Metals and metalloids are ubiquitous in soils, originating from bedrock and from human activities and infrastructure. These compounds can be toxic to humans and other organisms, and their soil distribution and concentrations at global scale are not well known. Hou et al. analyzed data from more than 1000 regional studies to identify areas of metal toxicity and explore drivers of these trends. They estimate that 14 to 17% of cropland exceeds agricultural thresholds for at least one toxic metal.
Microplastics have been found for the first time in human ovary follicular fluid, raising a new round of questions about the ubiquitous and toxic substances’ potential impact on women’s fertility. The new peer-reviewed research published in Ecotoxicology and Environmental Safety checked for microplastics in the follicular fluid of 18 women undergoing assisted reproductive treatment at a fertility clinic in Salerno, Italy, and detected them in 14.
While NGOs and Members of the European Parliament are calling for a ban on so-called "forever chemicals" in pesticides, only a few kilometres from Brussels, in Flanders, contamination is in full swing, even affecting organic farmers. PFAS (per- and polyfluoroalkyl substances) are chemicals used mainly for their water-repellent properties. Recent studies suggest that pesticide products may contain PFAS and that some active ingredients may meet the definition of a PFAS. This group of chemicals is a known threat to human health. Once in the environment, they are extremely persistent, earning them the nickname "forever chemicals".
Our study presents a global assessment of microplastic pollution’s impact on food security. By analyzing a comprehensive dataset of 3,286 records, we quantify the reduction in photosynthesis caused by microplastics across various ecosystems.
Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings—a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday. Carbon dioxide emissions from the building sector rose around 5% in the last decade when they should have fallen 28%, according to a new report by the United Nations Environment Program (UNEP).
His Royal Highness King Godwin Bebe Okpabi has carried bottles of water drawn from the wells of his homeland in the Niger delta to the high court in London. For the past three and a half weeks, lawyers for Shell have argued at the high court that their client cannot be held responsible for an environmental catastrophe in Ogale, which has suffered from decades of spills and pollution from oil extraction.
Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
Plastic pollution and forever chemicals are so widespread they’re even in the rain, putting public health and natural ecosystems at risk.
