How do climate changes affect health?
December 15, 2015
Climate changes often referred to as a change in our physical environments such as melting ice caps leading to rising sea levels and ultimately storms and global warming. Recent studies reveal the threatening evidence that along with affecting the physical surroundings it has incredible influence on human health. With every passing year, this threat to human health is increasing the rate of increasing global warming. As our life goes on in a cyclic way and climate has a direct influence on health and social life. When greenhouse gas level rises it trigger temperature to rise and higher temperature leads to alter weather patterns that cause crops failure, homelessness, and ocean acidification. Ocean acidification causes the marine ecosystem to change from its normal state. All these changes will ultimately lead to mass migration, social unrest, malnutrition that is the primary cause of several diseases, and displacement. All these factors are responsible for the change in climatic condition. The major impacts of climatic change on health are the increased rate of mortality. Extreme weather conditions also cause diseases. Disasters like Asian tsunami of 2004, and the number of people who have been killed in France due to heat-wave is numerous but, the indirect effect of weather change on health is equally significant. Gradual climatic change is affecting the human health. It has been estimated that in Europe, the prevalence of asthma has largely been increased over two decades because of major change in climate. The increase in heat level and ozone act together to worsen the state of human health. Studies indicate that pollution and higher temperature results in the decrease in heart rate variability, which consequently lead to death. Allergy has become a common disease from children to adults. It has to prevail from third world countries to super powers. It is due to the rise of carbon dioxide in the atmosphere and high temperature. A significant impact of climate change is on human society and economic development. Experts say that extreme weather conditions are ultimately leading us to the verge of malnutrition and affecting our mental health. According to a survey, in developing countries the rate of malnutrition is increasing dramatically because crops are failing. Moreover, when it rains, it takes away the topsoil that makes it even more hard to cultivate crops. Consequently, all these factors contribute to low food production that leads to hunger and malnutrition specifically in children.
