Over the last 50 years, the global climate is changing as the Earth becomes warmer. Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter- for instance changing the severity and frequency of health problems already exiting in that area, creating unanticipated health problems.
As per reports, if the climatic conditions continue to deteriorate, then between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhea and heat stress. Apart from this, waterborne and other vector diseases may also spread, problems with food supply may also occur. Also, vulnerable and poor populations are expected to be disproportionately affected by climate change, with rising food and water insecurity, higher food prices, loss of income and livelihood opportunities, negative health effects, and population displacement.
