Essay On Environmental Hazards on Human Health
Factors such as pollution, higher levels of noise, contaminated food, water and air are responsible for creating hazardous effects on human health. If the air we breathe is polluted and the food or water we consume contains microorganisms than we are likely to suffer from diseases. This can even reduce the life span among people.
For most people all over the world the greatest environmental health hazard is pathogenic organisms. People living in less developed countries suffer diseases caused by pathogens. Infectious organisms become the main cause of death and disease. A group of illness that is caused by infectious organisms is gastrointestinal infections. It indicates illness like cholera, diarrhoea and dysentery. This group of illness is responsible for causing more deaths in the world than any other group of diseases. Malaria is another infectious disease caused by the Anopheles mosquitoes. It is very common in Africa. Tuberculosis and other respiratory diseases are the other causes of death.
Toxic chemicals in environment are the source of concern especially among people of industrial countries. These chemicals lead in abnormalities in children during birth. 1960s in Europe, a pill was sold to the expected mother. It was sold without the Doctor’s prescription. When the women had children, they were born with defects such as small limbs. It is believed that thousands of babies were born with physical defects. The pill was so strong that just one pill was enough to bring about such condition.
Human body becomes internally polluted by the consumption of alcohol and other drugs. Alcoholism is considered as one of the most important cause of mental and physical disintegration. In many societies, alcoholism is a major cause for road and industrial accidents. It is also responsible for the breakup of many marriages. Regular drinking may cause serious liver disorders as well as disorders in other organs.
The quality of air especially in urban areas has become very bad. There are several toxic gasses present in air. Inhaling such air may cause irritation of respiratory tracks. There are suspended particles present in the air. These particles are very dangerous. People overlook this danger merely as the problem of dust. Dust has two main origins, natural or chemical. Natural origin includes dust storms in dried areas. On the other hand, chemical origin includes wood burning, diesel exhausts and coal fired power plants.
Self-medication creates hazards on human health. People have a tendency of consuming painkillers with slightest discomfort in body. Such pills are the fastest selling medicine all over the world. People take such medicines and think that they will not have any side effects. However, if painkillers are taken on regular basses, than there can be harmful effects on human health. Kidneys can be damaged. If many painkillers are consumed together than it can result in internal bleeding.
Therefore, there is a strong relationship between environment and human health. Environment can affect human health positively as well as negatively.
