Explain as to how the degradation in environment is affecting the Human Health.
The problems resulting from environmental change and its degradation, pose new challenges for traditional public health science. It is an accepted fact that, environmental degradation is contributing to human health threats worldwide.
These questions have aroused increasing interest in recent years. In the poorest regions of the world an estimated one in five children will not live to see their fifth birthday, primarily because of environment-related diseases. This tragedy translates into more than 11 million childhood deaths a year worldwide, mostly due to malaria, acute respiratory infections or diarrhea, all illnesses that are largely preventable.
* Environmental degradation is an important factor contributing to the burden of disease. 19%–25% of the burden of disease in developing world is linked to environmental factors. The annual cost of damage to health and quality of life due to environmental degradation; is estimated to be 1.8%–3.4% of gross domestic product in some countries. 43% of the children’s (0-14 years) mortality is attributable to poor environmental conditions.
* Thus, environmental degradation exerts significant pressure on human health. Exposure to air, water and soil pollution, to chemicals in the environment, or to noise, can cause cancer, respiratory, cardiovascular and communicable diseases, as well as poisoning and neuro-psychiatric disorders.
* Air pollution, in fact, is one obvious environmental health threat in many countries, contributing to a number of illnesses, such as asthma and in some cases leading to premature death. Of particular concern is the fact that children are more vulnerable to air pollution than adults, and increased rates of infant mortality have been recorded in highly polluted areas. Concerns about the impact of air pollution on health and the economy have resulted in measures to mitigate emissions of the most harmful pollutants, such as particle pollution (acids, organic chemicals, metals, and soil or dust particles) and ozone, which affects the respiratory system. Despite national and international interventions and decreases in major pollutant emissions, the health impacts of air pollution are not likely to decrease in the years ahead, unless appropriate
