Climate Change and Human Health: Impact on Emerging Diseases, Food Safety, and Water Security

Climate change and Emerging diseases: Climate change causes the emergence of new and spread of present infectious diseases .

• 1. Rising temperatures promotes rapid multiplication of most common bacteria like typhoid and virus like hepatitis. .
• 2. Urbanisation and construction activities promote sanitation issues causing increase breeding of mosquitoes . These mosquitoes thrive in hot humid climate . Presence of accumulated water in building , road , terraces , dustbins especially in rainy seasons are breeding ground for mosquitoes. Cases of mosquito borne disease like malaria , chikungunya , Zikavirus and dengue rise due these changes.
• 3. Frequent Migration of large population like construction workers and easy long distance travel promote spread of infections from far off places .

Climate change and food safety :

• Climate change compromises food safety by increasing the prevalence of foodborne pathogens, expanding the reach of toxins, and disrupting supply chain infrastructure.
• Rising temperatures encourage bacterial growth (e.g., Salmonella,).
• Higher temperature and humidity promotes growth of fungi on crops and superficial fungal infections in humans.
• Warming lakes and oceans cause toxic algae spread, seafood poisoning and spread of various organisms like vibrio.
• Rising CO2 levels makes water acidic preventing growth of shells in crabs, oysters and clams. Rising ocean temperature lead to increase shift of warmer marine species in previous cold areas .
• This leads to reduce catch of cold thriving marine species like sea bass and trout.

Climate change and water safety :

• Increase rainfall and flooding cause sewage overflow contamination of drinking water triggering endemics of typhoid , hepatitis, leptospirosis and other diarrhoeas diseases.
• Famine and water scarcity cause crop failure ,poor hygiene., food scarcity leading to malnutrition-and waterborne diseases.
• Extreme weather like heatwaves cause dehydration ,heat stroke or cardiovascular failure.
• Air pollution can cause respiratory illnesses like Asthma, COPD and some forms of lung cancers.

Building a climate resilient lifestyle :

• Reversing the adverse climate change is a slow process. Protecting us from climate change goes a long way in achieving a healthy life.
• Reducing waste of food and water reduces the pressure on limited natural resources .
• Recycling helps in reducing carbon foot print .
• The switch to renewable energy resources like solar power, energy efficient applications and organic fertilisers help to reduce exposure to harmful pesticides,pollution and preserve natural resources.
