Global Environmental Pollution and Its Effect on Life Expectancy Dr. M. A. Quader Abstract- Current status of global life expectancy increase is explained. Environmental pollution is a threat to human civilization, a threat to life expectancy. The loss of life years and life expectancy in the global context are identified and quantified. The potential gains in life expectancy are also identified and quantified. Keywords: life expectancy, pollution, effect of pollution. Terms LE Life Expectancy (years) LEB Life expectancy at birth(years) LLE Loss of life expectancy (years) YLL Years of life lost CD Communicable disease NCD Non communicable disease DALY Disability Adjusted Life Years I.

More than 7 million people die each year from air pollution, according to a new study. It is far more than the estimated 2.6 million people who have died from Covid- 19 since it was detected more than a year ago. Pollution is the world’s largest environmental threat to health, responsible in 2020 for an estimated 10 million premature deaths, or 15% of all deaths globally, and 275 million Disability-Adjusted Life Years. This is equal to 0.035 year life expectancy lost on global basis. Annual deaths due to environmental pollution world over are shown in the following table (Table 1.1). More than three fourths deaths occur due to air pollution. One fifth of the deaths occur due to water pollution. About 4% deaths occur due to land pollution. For better visualization, this is also shown in figure (Fig 1.1). Table 1.1: Global Deaths due to Pollution( 01 ) E As can be seen from the table, 76.17% of the deaths occur due to air pollution followed by water pollution. Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects. Water pollution causes typhoid, cholera, hepatitis and various other diseases and destruction of Ecosystems: Ecosystems are extremely dynamic and respond to even small changes in the environment. Water pollution can cause an entire ecosystem to collapse if left unchecked.
