💧 Chemeli’s Struggle: A Mother’s Fight Against Climate Change

Chemeli lived with her husband and two children in a small, low-lying neighborhood near an old riverbed. For years, she had managed her modest home with courage, finding happiness in small things despite the poverty surrounding her. But as climate patterns shifted, the rains that once nurtured her garden turned into devastating floods.

One monsoon evening, the water rose quickly, entering their house with terrifying force. Chemeli and her children climbed onto the wooden cot, while her husband tried to save their belongings. Within minutes, the muddy flood swallowed their kitchen, destroyed food supplies, and carried away schoolbooks. Her children cried in fear, clinging to her sari, while Chemeli’s husband struggled to keep them safe.

The flood left behind more than wreckage; it brought disease. Stagnant water in the lanes bred mosquitoes, and her little boy developed a high fever from dengue. The nearest hospital overflowed with patients, and the long wait broke her spirit. Her husband, who worked as a daily wage laborer, lost his job when factories shut down due to repeated flooding, pushing the family deeper into hunger.

At night, Chemeli lay awake, listening to her children’s coughs, wondering how climate change—something so vast and invisible—had entered her home and stolen their peace. Yet, she refused to surrender. She joined a women’s group in her locality that planted trees, cleaned drains, and demanded better flood protection. Through her pain, Chemeli discovered resilience, determined to give her children a safer tomorrow.

10 Deadly Ways Climate Change Can Kill You and Your Future

1. Extreme Heat – Prolonged heatwaves caused by climate change raise body temperatures dangerously, leading to dehydration, heatstroke, kidney failure, and cardiac arrest, especially in vulnerable populations like children, the elderly, and outdoor workers exposed to direct sunlight.

2. Air Pollution – Rising global temperatures intensify smog formation, dust storms, and wildfire smoke, worsening asthma, lung infections, and cardiovascular diseases, while prolonged exposure to polluted air silently damages respiratory systems and increases premature deaths worldwide.

3. Vector-Borne Diseases – Warmer climates expand habitats of mosquitoes, ticks, and flies, spreading deadly diseases such as malaria, dengue fever, chikungunya, and Lyme disease into new regions, increasing infections, hospitalizations, and deaths from preventable illnesses worldwide.

4. Water-Borne Diseases – Climate-driven floods, heavy rainfall, and rising water temperatures contaminate drinking supplies, spreading cholera, diarrhea, and typhoid, while stagnant waters promote pathogens, directly threatening millions without access to safe sanitation or clean water.

5. Malnutrition & Starvation – Global warming disrupts crop cycles, reduces yields, damages fisheries, and worsens droughts, leaving millions without stable food access, leading to undernutrition, weakened immunity, stunted growth, and increased deaths from hunger-related complications globally.

6. Extreme Weather Disasters – More frequent cyclones, floods, and wildfires destroy homes, hospitals, and roads, directly killing thousands, displacing millions, and leaving survivors vulnerable to secondary deaths from injury, disease, or starvation in chaotic conditions.

7. Sea Level Rise – Melting glaciers and thermal expansion of oceans cause rising sea levels, submerging coastal cities, eroding land, displacing populations, increasing storm surges, and creating uninhabitable conditions, leading to drowning, forced migration, and mass casualties.

8. Mental Health Impacts – Natural disasters, forced migration, and fear of climate uncertainty trigger eco-anxiety, trauma, depression, and suicide, silently taking lives, especially among farmers, youth, and survivors struggling with loss of family, livelihood, and stability.

9. Conflict & Violence – Climate-induced scarcity of water, land, and food worsens poverty, forcing migration, sparking resource conflicts, wars, and violence, where vulnerable populations suffer deaths from starvation, displacement, or killings in unstable regions worldwide.

10. Infrastructure Collapse – Rising temperatures, floods, and storms weaken bridges, hospitals, and power grids, causing medical emergencies, delayed care, transportation breakdowns, and indirect deaths during disasters, as systems critical for human survival fail catastrophically under climate stress.

Temperature Rise vs Climate Change Effect

Temperature Rise	Climate Change Effect
+1°C increase	Frequent heatwaves in cities
+2°C increase	Severe drought and crop loss
+3°C increase	Rising sea levels are flooding towns
+4°C increase	Mass extinction of species
+5°C increase	Uninhabitable regions worldwide

Frequently Asked Questions

Q 1: Can climate change directly kill people?
Climate change doesn’t kill directly, but its impacts, like extreme heat, floods, and disease outbreaks, significantly increase risks of death and suffering worldwide.

Q 2: How does heat from climate change cause death?
Extreme heat triggers dehydration, heatstroke, kidney failure, and cardiac arrest, especially among vulnerable groups such as children, the elderly, and outdoor workers under direct sunlight.

Q 3: Can rising sea levels kill humans?
Yes, rising seas cause flooding, coastal erosion, and storm surges that displace millions, drown communities, and create unsafe living conditions, leading to many casualties.

Q 4: Does climate change increase disease spread?
Yes, warmer climates expand mosquitoes and ticks, spreading malaria, dengue, and Lyme disease, leading to higher infections, hospitalizations, and preventable deaths across new global regions.

Q 5: How does climate change affect food security?
Global warming reduces crop yields, damages fisheries, and worsens droughts, causing malnutrition, weakened immunity, stunted growth, and deaths from hunger-related complications worldwide.

Q 6: Are mental health deaths linked to climate change?
Yes, climate-driven disasters and displacement increase eco-anxiety, depression, trauma, and suicide, silently taking lives among vulnerable populations like farmers, youth, and disaster survivors.

Q 7: Can extreme weather events kill directly?
Yes, disasters like cyclones, floods, and wildfires destroy homes, hospitals, and roads, causing immediate deaths while survivors often face starvation, disease, and further fatalities.

Q 8: Does climate change worsen air pollution deaths?
Yes, rising heat intensifies smog, wildfire smoke, and dust storms, worsening asthma, lung disease, and heart problems, leading to millions of premature deaths globally.

Q 9: How does conflict from climate change cause deaths?
Scarcity of water, food, and land sparks conflicts, migration, and wars, leading to violence, starvation, displacement, and killings in unstable and vulnerable regions worldwide.

Q 10: Can collapsing infrastructure during disasters kill people?
Yes, floods, storms, and heat damage power grids, bridges, and hospitals, causing medical emergencies, delayed treatment, transportation failures, and indirect deaths during major climate disasters.

Conclusion

Climate change is not a distant threat but a present danger affecting every aspect of human survival. From deadly heatwaves to food insecurity, rising seas, and collapsing ecosystems, its impact is devastating. Protecting our planet means protecting ourselves and future generations. Urgent action through sustainable living, renewable energy, and global cooperation is vital. The choice is ours—either confront climate change today or allow it to determine a darker, more fragile tomorrow.
