Key negative effects of climate change on society

Public Health Issue

As the environment begins to experience an unprecedented change in temperature, people across the globe have started to see a huge impact triggered by climate change. Bearing the brunt of the negative effects of climate change, human lives have become especially susceptible to several health hazards. Here’s why this increasingly warmer planet makes the public health issue a key concern.

Polluted, warmer air

A warmer environment increases the amount of smog or ground-level ozone in polluted areas, which is created when pollution from factories, cars, and other sources react to heat and sunlight. Put simply, the hotter things get, the more the smog. This makes it a public health issue. Smog triggers asthma attacks and other lung problems and worsens the condition of those who suffer from pulmonary or cardiac disease. Rising temperatures also increase airborne pollen, which is bad news for people suffering from allergies.

Higher death rates

One of the most detrimental effects of climate on health happens because of increased temperature. This spike in temperature impacts human lives to a great extent—especially the elderly, the children, and the low-income communities. Living in high temperature for longer days causes severe health consequences. Higher temperature is directly related to various life-threatening illnesses including heatstroke, heat exhaustion, and cardiovascular diseases.

While climate change and its effects on health are perhaps among the biggest threats to human lives, addressing it needs a unique approach that reinforces the idea that humans aren’t a separate entity outside this environment.
