Health Effects of Climate Change
July the 29th is World Health Day. The objective chosen for this year is to get people involved in the campaign to protect against the health effects of climate change. There is already evidence of health problems related to climate change. More people are dying form extreme heat, and diseases spread by insects are also on the rise. Climate change has increased the risk of natural disasters, especially severe dry weather, wildfires, major storms and floods. Disasters like these can kill directly or indirectly. People can die or get sick from food shortages or conditions like the spread of disease. Researchers in Canada predict that temperature increases there will spread insects farther north. These insects can carry disease. Climate change will lead to an increase in outbreaks of diseases that can be carried in water and food. Flooding, heavy rains and warmer temperature are linked to the spread of bacteria, viruses and other organisms.
