The climate change is connected with change in worldwide weather and an increase in average temperature. Climate change is not only includes the increase in global average temperature, but also the effects of this on climate. Not only the humans that are affected by the climate change. Increasing ocean temperature leads to increase the coral bleaching those results from the loss of a coral’s symbolic algae. The global warming which causes forest fires and it destroys the wildlife habitats around the world. Climate change having socio-economic and politics impacts too. Food security is one of the major impacts of climate change. Climate change affects the social and environmental determinants of health-clean air, safe drinking water, sufficient food and secure shelter. Between 2030 and 2050, climate change is expected to cause approximately 250000 additional deaths per year from malnutrition, malaria, diarrhoea and heat stress. Reduced emissions of greenhouse gases through better transport, food and energy-use choices can result in improved health, particularly through reduced air pollution.
