Climate change is not just an environmental issue—it is a public health crisis. Rising temperatures, extreme weather, and ecosystem disruptions are creating new and intensified health risks worldwide.
Heatwaves cause heatstroke, dehydration, and increased mortality, especially among the elderly, children, and outdoor workers. Warmer climates also expand the range of disease-carrying insects like mosquitoes, spreading illnesses such as malaria, dengue, and Zika virus.
Air pollution from fossil fuel burning worsens respiratory diseases such as asthma and contributes to millions of premature deaths annually. Climate change also threatens food and water security, leading to malnutrition and contaminated water supplies.
Mental health is another overlooked consequence. Communities affected by floods, wildfires, or displacement suffer from stress, anxiety, and trauma. The term “eco-anxiety” is now widely used to describe the psychological toll of climate awareness itself.
Healthcare systems, already under pressure, face increasing burdens from climate-related illnesses. Building climate-resilient health systems, reducing emissions from healthcare, and prioritizing preventive care are essential steps. Addressing climate change is, ultimately, an act of protecting human health on a global scale.
