Food systems are key drivers of the world’s most urgent challenges, from chronic diseases and rising inequality to accelerating climate change and biodiversity loss, according to the 2025 EAT-Lancet Commission on Healthy, Sustainable, and Just Food Systems. The new report finds that while the world produces enough food calories for everyone, nearly 3.7 billion people are without access to a healthy diet, meaningful wages, or a clean environment. At the same time, food production is a significant contributor to environmental degradation, accounting for nearly 30% of global greenhouse gas emissions and pushing the transgression of the planetary boundaries (climate change, biodiversity loss, land use change, freshwater consumption, nutrient pollution, and novel entities such as pesticides and antibiotics). This crisis of inequity and environmental harm threatens human health and the resilience of planet Earth.

Countries with the highest reported levels of hearing loss also have the lowest reported use of hearing aids, finds international research published in the open access journal BMJ Global Health.

Early medical abortion at home up to 12 weeks of pregnancy is safe, effective, and comparable to hospital care, finds a 5 year review of cases in Scotland, where this timeframe is legally permitted, and published online in the journal BMJ Sexual & Reproductive Health.

A study comparing evacuation patterns in response to two 2024 hurricanes, Milton and Helene, found that people in coastal areas with frequent hurricane exposure were much more likely to travel out of harm’s way compared to people in inland areas who were more likely to stay put. Researchers at Columbia University Mailman School of Public Health led the study. Their findings appear in the journal Environmental Research Letters.  

Catastrophic wildfires – those causing massive damage and soaring suppression costs – are increasing in frequency and intensity worldwide, a trend expected to worsen with climate change. In a Policy Forum, Robert Gray and colleagues use British Columbia (BC), Canada, as a case study of a government at a crossroads: continue reactive spending on suppression and recovery or invest in strategies to reduce future wildfire risk. “Although we focus on BC, this same tough question, along with lessons learned and our main recommendations, apply to regional and national governments in dozens of countries,” Gray et al. write. Over the past decade, BC has lost more than 7 million hectares to wildfire, with suppression and recovery costs topping $4.8 billion. Indirect costs, including health impacts and economic disruption, are far higher. Here, the authors argue that governments like BC are faced with an important policy choice; either continue to focus on response and recovery, or embrace proactive, long-term fire mitigation and prevention. Gray et al. highlight that scaling up wildfire mitigation requires public and political support for sustained, multidecade investments, along with cost-management strategies, yet governments continue to prioritize reactive spending despite evidence that prevention is far more cost-effective. They propose four recommendations: set clear resilience goals based on economic and risk analyses; foster public understanding and support for short-term sacrifices like prescribed burns; implement collaborative, hands-on landscape-scale interventions with scientists, Indigenous leaders, industry, and communities; and leverage public concern and scientific evidence to secure long-term political commitment and funding for preventive wildfire management.
