Air Pollution: One of the most common environmental issues that harm human health is air pollution. Exposure to harmful pollutants in the air can lead to various respiratory diseases such as asthma, bronchitis, and even lung cancer. Fine particulate matter, for example, can penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, and respiratory infections.

Water Pollution: Contaminated water is another environmental issue that poses a threat to human health. Drinking or bathing in polluted water can cause a variety of health problems, ranging from diarrhea and vomiting to life-threatening illnesses like cholera, dysentery, and typhoid fever. Pollutants such as heavy metals can also accumulate in the body over time, leading to serious health issues including kidney damage and neurological disorders.

Climate Change: Climate change is an environmental issue that can indirectly harm human health. Rising temperatures can lead to heat strokes and dehydration. Changes in climate patterns can also lead to the spread of vector-borne diseases like malaria and dengue fever. Additionally, extreme weather events such as floods and hurricanes can cause injuries and loss of life, as well as mental health impacts such as stress and trauma.
