Public transport systems are critical to economic productivity, urban mobility, and environmental sustainability, but they also present complex safety, health, and operational risks. Accidents, infrastructure failures, overcrowding, and infectious disease transmission all pose potential threats to passenger safety and public trust. Meanwhile, climate change adds further stress, with extreme weather events disrupting services and damaging…

Bovine spongiform encephalopathy (BSE), or “mad cow disease,” remains one of the most notable examples of how animal health risks can escalate into public health and economic crises. Linked to variant Creutzfeldt-Jakob disease in humans, BSE outbreaks in the late 20th century caused widespread alarm, disrupted international trade, and reshaped food safety regulation globally. The…

Country foods — the traditional foods harvested, hunted, or fished by Indigenous and rural communities — are central to cultural identity, nutrition, and food security. They provide essential nutrients, support community resilience, and reinforce connections to land and heritage. However, these foods can also present risks due to environmental contamination, overharvesting pressures, or changing ecosystems…

Pressure vessels — including boilers, storage tanks, and industrial process equipment — are indispensable to modern industry but carry inherent risks if improperly designed, maintained, or operated. Failures can result in catastrophic explosions, toxic releases, or widespread service disruptions, with serious consequences for worker safety, public health, and infrastructure resilience. Regulation of pressure vessels is…

Mitigating flood risk goes beyond response and recovery — it involves proactive strategies to reduce the likelihood and severity of impacts before disasters occur. Measures range from physical infrastructure, such as levees, dams, and green stormwater systems, to policy interventions including zoning, building codes, and managed retreat. Climate adaptation and resilience planning now make flood…

Artificial intelligence (AI) has become a transformative force in decision-making across sectors ranging from healthcare and finance to energy, transportation, and regulation. The promise of AI lies in its ability to process vast amounts of data quickly, uncover hidden patterns, and support evidence-informed decisions in ways that humans alone cannot easily achieve. Yet the risks…

Manganese is an essential trace element necessary for human health, industrial processes, and steel production, yet it also poses risks when exposure levels exceed safe thresholds. Occupational exposure in mining, welding, and manufacturing, as well as environmental contamination from industrial emissions or water supplies, can lead to neurological effects, including manganism — a Parkinson’s-like disorder.…

Wood smoke is a significant contributor to air pollution, especially in regions where wood burning is used for residential heating or where wildfires are prevalent. Fine particulates and toxic compounds in wood smoke are linked to respiratory illnesses, cardiovascular disease, and increased mortality. In addition to health impacts, wood smoke contributes to climate change through…

Lithium has become a strategic material in the global transition to renewable energy, powering batteries for electric vehicles, consumer electronics, and grid storage systems. Demand is growing exponentially, raising both opportunities and risks. While lithium plays a central role in decarbonization, its extraction, processing, and disposal raise concerns about environmental impacts, worker safety, and geopolitical…

Blood and blood products are essential to modern healthcare, supporting surgeries, trauma care, cancer treatment, and the management of chronic diseases. Ensuring the safety and adequacy of the blood supply is therefore a critical public health priority. Risks arise from infectious disease transmission, donor eligibility challenges, storage and handling practices, and supply chain vulnerabilities. The…
